GameBro (presumably a parody of GamePro) is a Homestuck that John Egbert and Dave Strider read. Though both of them believe that the magazine isn't worth the time, Dave reads it - and writes satirical online reviews of it - for ironic purposes.in
The latest issue had a bad review of Sburb; though the author of the article , he gave it one and half hats out of five for its inability to "thrash anything" before going into a discussion of the sweet times he had with his brosephs recently. John burns the magazine in the living room fireplace later on.
Every issue is guaranteed to be printed on 40% recycled asbestos:
The Strider's living room is littered with back issues of GameBro. Dave captchalogues and then punches a copy of GameBro, finally "upgrading" his Alchemiter to an utterly useless heap of shit with it.
A vintage copy of Gamebro was created with the Alchemiter by Dave, using the Timetables along with a regular copy of GameBro. It is unknown what is within the issue.
GameGrl is a different edition of GameBro, possibly by the same creators, existing only in the post-scratch universe. It seems to be more female-oriented than the original, given its title and pink fonts. An issue of GameGrl is shown on Jane Crocker's desk, and another near Roxy Lalonde's game consoles.
