Well, I can't get it run. I'm still on ME, but will eventually upgrade to XP first chance I get some extra money. They've certainly f##ked up a good chunk of potential market share by excluding a big number of people who might have been drawn to this game. Ironic how Eid-ass and ISA, in their attempt to 'mainstream' this game by bifurcating it for both console and PC end up throwing the plan out of balance by crapping on a good size PC market. Splinter Cell and Silent Hill 2 & 3 had similar graphical effects and they supported earlier OSs.
