While Grand Theft Auto 5 was revealed at Sony's E3 press conference, the console announcements played second fiddle to the potential afforded by the PC version. As great as Grand Theft Auto 4 is on consoles, the game's lifespan on PC extends far past its console cousins (KAHZEEN) thanks to the countless mods enterprising players have applied to the game. From the functional (boosting to new-gen-level textures) to the insane (playing as a horse , driving a piano car, or removing all vehicle friction), PC-owning GTA fans get far more choice. Sure, many PC games have mods, but Rockstar's series is as much about messing around, causing chaos (aspects significantly enhanced by mods), as it is about serious crime.
While Rockstar has yet to announce how mod-friendly GTA 5 is, many sensibly assume it'll have a thriving PC community. I just hope the developer will try to share the love with consoles, perhaps vetting and aiding community members in bringing content to the PS4 and Xbox One, much like Valve did with Left 4 Dead 2's Cold Stream DLC.
