lowyhong: Not a single mention of SSI's AD&D games? I am disappoint!
tomimt: It would be so sweet to get a decent collection of SSI gold box games.
If GOG was able to finagle an old-school SSI collection in one handy installer for $5.99 like
AD&D Masterpiece Collection or the
Forgotten Realsm Archives (of which there were multiple compilation volumes released in the 90s), that'd be pretty awesome, for the childhood nostalgia if nothing else.
As far as other insta-buys, I'd say American McGee's Alice and Privateer 2. I already own physical disc copies of things like Thief and System Shock 2 so they aren't essential. I actually wouldn't mind buying Diablo 1/Hellfire again, but it'd probably be a cold day in hell before Blizzard allows such a backlog atrocity to occur; or about the same chance as the old Star Trek games getting digital distribution I'd reckon.
