I'd like to see I-War 1 aka Independence War on gog.com. This game is really hard to get and is considered a real space game classic. I'd love to have it in a version that runs under XP.

I want to see Command and Conquer: Red Alert, the Win95 version. NOT the GDI vs NOD, the Soviets vs Allies.
some people get those confused for some reason...

The one on the "what's this game" thread that I unfortunately cannot mention.

Neither of these games are on steam. Everyone regards these as classics, and I'd love to try them.

GTA 1 & 2 are given away by rockstar on their site, I believe.

Hell Yes! I so want to play Raptor again, that game was sooooo awesome. Tyrian was ok but Raptor that game was the best.

But with the gog installer and some nice extras it would be fine as a free game on gog

darkstone. it doesn't work on xp, and i heard it does ok on vista. but i think the dev and publishers are defunct.
