All in all, their compression numbers are not really anything of the sort. Procedurally generated textures are interesting from a technical standpoint, but not from an artistic standpoint. Honestly, have a look at the textures in that game. They're generic, repetitive, they aren't high resolution, they aren't really even "lifelike" in any way, shape or form. Sure, they're bumpy, but so is the sand texture in FarCry and the sand looks better... Also, look at the level modeling, even the 'characters' are procedurally generated and are done at very low poly levels.
All of us technoweenies like the conceptual part of the game, but no "ordinary" Joe Gamer out there is going to forgive the ugliness because it's uber technical. Joe Gamer only cares that his characters look realistic or at least believable, and his textures aren't generic and "computer generated looking".
