I remember the first one having display problems with certain video cards; the publisher's idea of "support" was to say "take the game back to the store you bought it from and ask for a refund." If GOG got the original game and it worked properly I'd try it, since I've always wanted to play it.
GOG, please grab I.G.I. the First right quickly! I always wanted the two I.G.I. games. Spent hours alone just playing the demo for the first game when it was released. I would prefer getting the first game...first....
I remember I tried to run IGI 1 on XP on 3 different machines even on older video cards (GeForce 4MX, GeForce 2, Radeon 9800 Pro) but to no avail (the game did run but with graphic problems such as no HUD which made the game pretty much unplayable) . The only way was to run it on windows 98 with older video drivers. If guys at GOG will manage to update it to run under newer systems and will release it here I will definately buy it. Way better than IGI 2! Keep up the good work GOG team!
