The third series is Steam Train, where Ross O'Donovan an Avidan plays PC games. Sometimes, of the of two or both will play with any one or more than one of the following: Hanson, Barry Kramer, Suzy Berhow. In 2015, it became just two people playing games.
The fifth series is Hunting Monsters, where Berhow, Hanson, Kramer, and O'Donovan play "Hunting Monsters 3" (Season 1) and "Hunting Monsters 4" (Season 2). Avidan provides commentary, like a narrator.
The sixth series is Table Flip, where Kramer and Berhow play games, that are not video games, with guests.
The seventh series is Grumpcade, alternately spelled, "Grump Cade", where any combination of people, excluding Hanson and Avidan, play console games.
The Game Grumps began as a result of an argument between Hanson and Jafari. They were playing Super Smash Brothers Brawl with friends and had an intense debate about whether the characters Wolf and Fox were clones or not. When someone complained that the two should stop being so grumpy over the game, Hanson suggested he make a podcast called, "Game Grumps", and the idea evolved into the creation of the channel.
The channel was created on July 10, 2012, and the first video was uploaded on July 18. Since beginning the channel, the channel has accumulated a huge fan following from Egoraptor fans, JonTron fans, and gamers in general. The Game Grumps play games and commentate them in the same vein as a "Let's Play" channel, though they usually insist they aren't a Let's Play channel (there has been at least one occasion where Jafari refers to GameGrumps as a Let's Play channel). Given the fact that the Grumps do not complete most games they begin, this holds true. The Grumps discuss various topics, usually revolving around the game they are playing, game design, their channels, social lives, and pop culture. Currently, the channel has over 1,750,000 subscribers and over 750,000,000 total video views.
Early in Game Grumps, Jafari and Hanson generally played games that one had played before, and wanted to share with the other, such as Jafari's Banjo Kazooie, and Hanson's Mega Man 7, or both had played and enjoyed, such as Kirby Super Star. In September 2012, the Game Grumps began receiving games in their PO Box from fans, and even more as time went on. Their variety of games became more diverse, and the amount of time spent playing each game generally decreased; many games played were only one-offs, or series only lasting about three episodes.
Since the beginning of GameGrumps, the channel has had a strong and creative fanbase. Their fans have made a lot of Game Grumps-related content. Game Grumps fans have made a lot of fanart for the Grumps. The fanart is generally either an illustration of a moment from an episode, or simply drawings of Jafari and Hanson. The fans have also made a notable amount of Rule 34 fanart of the Grumps, which they have acknowledged. Some fanart has been posted on the Game Grumps Facebook page. Another form of fan content is remixes. The remixes are generally created by editing audio from Game Grumps episodes. The first notable example of a fan remix is Waterflame's pause balls remix, which was mentioned and sung in an episode of Game Grumps. Fanmade Game Grumps Animated have become a very common creation among fans. These animations show parts of the Game Grumps' playthrough, generally either placing Hanson and Jafari inside the video game, or showing them on their couch playing the game. These animations were done even before Hanson had made some for the Game Grumps channel, although they became more common afterwards.
When Game Grumps began, Jafari edited the videos, and he and Hanson shared management of the GameGrumps channel. Late in September 2012, Kramer took over the role of editor of GameGrumps, as well as every role besides the actual recording, including uploading videos and managing playlists. This was done to allow Jafari and Hanson to focus more on their main channels. Kramer copied Jafari's style of editing to keep his role a secret, in fear that fans would not feel comfortable with somebody else editing the videos. Fortunately, fans responded positively to Kramer, and he has become as popular as Jafari and Hanson.
In January2013, the Game Grumps attended their first convention together, MAGFest 11 (Hanson had gone to conventions before, without Jafari). They held their first Game Grumps panel, where they answered many questions about the show and announced many upcoming events.
Shortly after MAGFest, the Game Grumps had their first guest star on the show, Grant Kirkhope, a composer for many Rareware games, in a new series called Guest Grumps. The episode was released on March 25, 2013.
On June 25, 2013, it was announced that Jafari was leaving the show, and that Avidan of Ninja Sex Party was taking his place. On the same day, the Game Grumps channel received a spin-off show, Steam Train, starring Avidan and O'Donovan.
The original trailer for Steam Train was uploaded (but taken down shortly after) on RubberRoss.[Citation Needed] In this trailer, it was revealed that Avidan was originally only supposed to appear on Steam Train with O'Donovan, while Hanson and Jafari continued Game Grumps. However, when Jafari left the channel, Danny was asked to fill in as the new Not-So Grump. Jafari stated on his own channel that he left to concentrate on his main channel as his video schedule was very slow during his time on GameGrumps. Jafari has confirmed several times that he will not be returning to GameGrumps.
On August 23, 2013, Steam Rolled was launched. Originally a competitive version of Steam Train, similar to Game Grumps VS, the first episode featured Quake III Arena, with Hanson, Avidan, O'Donovan and Kramer as players. Suzy Berhow also joined Steam Rolled shortly after this episode, replacing Avidan, on August 26, playing Mario Party 4.
On October 25, 2013, a temporary Halloween themed Game Grumps and Steam Train series called, "Ghoul Grumps" and "Scream Train" began. This saw the beginning of several holiday-themed spin-off shows. On December 22, 2013, another spin-off series was aired; Jingle Grumps and Steam Sleigh. There has been similar spin-off series on Valentine's Day and St. Patrick's Day, suggesting that there will be other holiday-themed series as well.
In January 2014, the Game Grumps attended MAGFest 12. Hanson, who had previously expressed uncertainty about another convention, hosted a Game Grumps panel with Avidan. There was also a Ninja Sex Party/Steam Train panel with Avidan, O'Donovan, Kramer, Berhow and Ninja Brian.
"Do you guys like football. I kinda like football," said by either Hanson or Avidan in Maniac Mansion: New Kid - PART 3 - Game Grumps. At this time, it is unknown which it is because they also used a voice modification to change the voice.
"Barry says the things I am saying are getting too long. Do you think so? Like, comment, and subscribe," said by either Hanson or Avidan in Maniac Mansion: Special Delivery - PART 4 - Game Grumps. At this time, it is unknown which it is because they also used a voice modification to change the voice. It is most likely Hanson, as he says that last sentence more often than Avidan does on the show.
"Inky was the best ghost in Pac-man," said by either Hanson or Avidan, the other then replies, "No, he wasn't," in Maniac Mansion: Finale - PART 5 - Game Grumps. At this time, it is unknown which it is because they also used a voice modification to change the voice.
"Bananas are Delicious," said by either Avidan or Hanson in Goosebumps HorrorLand - Game Grumps. At this time, it is unknown which it is because they also used a voice modification to change the voice.
"[In a parrot voice] Babies could play this game," said by Hanson. It is followed by "Yes, they could," said by Avidan. Hanson then says, still using the parrot voice, "Babies." That is then responded with, "Okay," by Avidan in Dead Rising: Mowing the Lawn - PART 4 - Game Grumps.
"[Yoda impression] mm, how did the sarlacc pit end up pooping out Boba Fett?" said by Hanson. It is then replied with, "How?" by Avidan. Still doing his Yoda impression, Hanson says, "With Sarlaxatives. Mm." Avidan then replies, "Oh, god. Funny joke." Hanson, still doing his Yoda impression, says, "Funny Joke!" Avidan then says, "Jesus." This is featured in Dead Rising: Zombie Hornets!! - PART 6 - Game Grumps.
"Randal Stephenson go to your room. Think--" said by Hanson. Avidan interrupts, in a kid voice, "But mom, dad." Hanson replies with, "Do it again." Avidan replies, in his normal voice, "Okay." Hanson then says, "Randal Stephenson go to your room!" Avidan replies, again in a kid voice, "But mom...dad... sorry, it's dark in here." The two start to laugh. This is featured in Cursed Mountain: Legit Fear - PART 2 - Game Grumps and I Spy Spooky Mansion - Game Grumps. This is the first message to be repeated on Ghoul Grumps.
