When it comes to PC games, one thing the platform has always had over its console brethren -- other than better graphics -- is mods. Since Rage is an id Software game, creative director Tim Willits has told PC Gamer that the PC version will ship with full mod-making and level building support.
In the words of Willits: "All you need to do is Pull down the console, type 'id studio', then press enter. Then, bam, there’s all the tools we use."
Can't wait for someone to mod the game into an idTech5 version of Doom, Rise of the Triads, or ehm, Borderlands.
