staticblast: Maybe, but that largely depends on which features you are using that drive the higher version requirement. For instance, if it's a necessary thing to facilitate the switch between old-style and new-style, that would present an almost insurmountable challenge.
berarma: Knowing that graphically more demanding games like Quake 3, 4 or Doom 3 used OpenGL 1.x, it seems to me that GF requiring OpenGL 3.3 is an absurd requirement. The same with the minimum 4GB RAM requirement. They're acting like lazy developers or hardware sellers.
Truth be told, they *kind of have* to be hardware sellers, right now... the Sony team that worked with them to make the PS4 and Vita versions did pretty much all the job, and that's why I assume the game requires OpenGL 3.3 (a standard feature of the PS4 and the Vita): Double Fine were just lazy and basically put the game the Sony team developed right on the PC, with minimum-to-no optimization, because "modern consoles are basically PCs". So, since the Sony team had most of the job, Double Fine must be at least a bit obliged to sell those few extra PS4s and Vitas that Grim Fandango might turn out to be a system-seller for. Which, in my opinion, isn't that much, the PlayStation crowd never struck me as the target audience for Grim Fandango. Nor the "PC MASTER GRAPHIC WHORES RACE", which are the only ones with good enough GPUs to run a game that could have run on a 2002 machine, from the looks of it.
