The videos generally only feature game play footage, with few exceptions. Unlike other popular let's players, such as Markiplier and PewDiePie, the Game Grumps do not use a face cam. Most series are recorded in chunks of seven episodes at a time, which allows them to release one series throughout the week. Episodes are generally about ten minutes long, but vary in length, with some episodes reaching over an hour. The Game Grumps play a video game, usually a console game with occasional exceptions, and commentate over the footage. In the summer of 2016, Kevin resigned from the Game Grumps channel, and Matt and Ryan of SuperMega became the new editors of Game Grumps. Ever since, they haven't done another Toon Grumps episode so far, and revealed that they lied about putting an end to their Let's Play series. As it was April Fools' Day, they were fibbing that they canceled Game Grumps and Steam Train, in order to go back making animated videos. On April 1st 2015, Arin and Ross introduced a currently single-episoded spin-off called Toon Grumps. Late in 2014, Kevin was announced to be taking over the role of editor of Game Grumps from Barry. In February 2014, Valentine's Day-themed Date Grumps debuted, with Arin's wife Suzy appearing in place of Danny. In December 2013, a similar Christmas-themed Jingle Grumps debuted.

Unlike Game Grumps VS episodes, Ghoul Grumps episodes are still considered to be Game Grumps episodes and not their own show. The only differences between Ghoul Grumps episodes and regular Game Grumps episodes are branding and generally the games played on the show are Halloween or scary-themed. In October 2013, Ghoul Grumps, a cosmetic change for Halloween, debuted. On June 25, 2013, it was announced that Jon would be leaving Game Grumps in order to focus on his own show JonTron, and that Arin's friend Danny from Ninja Sex Party would be serving as his replacement. In September 2012, Barry took over the role of editing Game Grumps videos from Jon. The show shares the same time slot as Game Grumps.

The show is virtually the same as Game Grumps with the exception that the Game Grumps play two-player versus games. On August 22, 2012, Game Grumps VS, a spin-off of Game Grumps, debuted. This idea evolved into both the Game Grumps channel and Let's Play series. A friend of theirs said they should make a podcast where they talk it out, and Arin came up with the name Game Grumps. Brawl and whether or not the character Wolf was a clone of Fox. The idea for Game Grumps proper came from an argument between Arin and Jon, who were having a debate about the game Super Smash Bros.
