It's lack of effort to trying to break the rut of games is why Crytek keeps selling theirs. If I had to choose between Rage and Crysis 2, I'd pick the latter because at least right now, NYC isn't being raped to death just yet. I can just play Fallout 3 to get my Wasteland fill. Not to mention Rage will also have New Vegas to go up against. Seriously id, if you are going to come back into the ring, don't do it as a copycat. At least pick a genre that isn't being used just now.
Why not revive Hexxen?
Id started work on their "copycat" about the same time Bethesda started on Fallout 3. Bethesda used a middleware engine which they also used for Oblivion and got it out the door. Id developed a new engine. I love Fallout 3. In spite of the game engine. I suspect I'll like Rage as a game, and be a lot happier with the tech it runs on. As for Hexen, that was a Raven Software game. Id engine, different developer -- the same developer that id used to do Quake IV. They have always had a pretty close relationship. Personally I'd love to see a Hexen III. Hexen II is one of my favorite all time games. Hopefully Raven will dust it off and carry it forward. First Person, RPG elements, swords and sorcery. *sigh* I can hope...
