Games you'd love to buy digitally

I played Sid Meier's Alpha Centauri and its sequel Alien Crossfire enough to know I love them now they won't run on my computer I wish they were on steam or something so I could play them a bunch. They were games made in between Civilization 2 and 3 set in Space after the space race in Civilization when you reached Alpha Centauri.  Just wondering if there are some games that other people love can't play anymore and would buy immediately if they were available digitally?

Sim Ant.
 
Though to be honest, I doubt I'd pay more than 2 dollars for it, and I'd much rather a remake.

Same for me I would love a redux for my game.

I wish SWAT 3 was on GOG or Steam.

I am waiting for GOG to offer a Win7-compatible version of Planescape Torment. I'd totally buy that.

DJ Hero

Basically any import games that cost upwards of $90 to import here.

The SWAT games and Grim Fandango.

Aliens vs Predator 2

Take 2's "Ripper". That was one heck of a FMV game and brilliantly executed. Hopefully GoG gets hold of it sooner or later, considering they've snagged quite a few of the good old FMV games of the 90's. 
 
I'd also like a version of Westwoods Blade Runner since getting it to run on Win7 is quite the hassle.

RockBand 2 would probably be the best game to be able to boot-up whenever. Also, FFIX :)

" Grim Fandango. "

I'm still waiting for Sim City and Sim Tower to appear on Steam. I don't want to use EA's shitty service.

none. I'm against buying digital copies of games because:
you won't have them permanently
I like hard copies

All the Wing Commander games.

Sim Farm. That game is amazing :D
There are tweaks to get any old game to run in Windows 7.
For example, I play Deus Ex on windows 7 64 bit without a hitch :D

If there is a game that I want digitally, its easily attainable.

Ultima VII
 
One that works exactly like it used to back on my old 486. You can kind of get it running now with Exult, but the sound doesn't work, and it plays kind of weird.

Just like warhawk, im hoping MAG gets on PSN soon. i still have some cash in my wallet.

Thief
Dungeon Keeper
Homeworld
Planescape: Torment.
 Wizardry
Quest for Glory

All of the "Fury" flight simulator games for nostalgia's sake. 

Warcraft:  Orcs and Humans, without having to use dosbox, and with a slightly modernized interface and multiplayer support.  Basically like Warcraft II Battle.net edition but for Warcraft 1
