I've got all the Total War games, save for the Empire DLC. They'd make great additions to this site. Although, I have to say I prefer Medieval 2 to Rome or the first Medieval. Rome's campaign had a tendency to inexplicably disintegrate after a while. Which is hardly encouraging given the amount of turns required.

Sid Meier's Alpha Centauri with the Alien Crossfire expansion. --- IMO this was the best strategy game I've come accross. Civilization III and Civilization IV pale in comparison to this. Extremely addicting to point where only one game so far has proved more addicting. (World of Warcraft) To me anyway.
Rollercoaster Tycoon 1 and 2 (Not 3 so much) --- Another addicting game. one of the best economic simulations ever made. (Ranks right up there with SimCity 2000.) Each scenario was a joy to play. (RCT3 had different AI where a lot of people didn't ride your rides. The DEMO of RCT3 had better AI, or so it seemed. Really a letdown.)
Kohan series --- A good RTS that pretty much introduced "Squad-level" units that you could customize. (I never seen it before Kohan) It's A system that I saw later in Dawn of War and Company of Heroes.
An offline single player version of World of Warcraft with a simulated Auction House and soloable RAIDS? I usually play it single player anyway. (Henchmen like in Guild Wars would work) Just can't RAID or do instances of my level without grouping. I've grown tired of grouping over the years. Too much drama. If I want multiplayer I go see Left 4 Dead for my fix. Instant groups in that game. Or maybe Oblivion with WOW's interface and combat. Ignore this last paragraph please!!

Command: Aces of the Deep
Simply put, this is the "Red Baron" of the sea... a master piece of a game, dynamic campaign, immersion, etc.....

1) Betral At Krondor - CD version via DosBox
One of the best RPGs of all time.
2) Star Trek: Starfleet Command III
One of the best Star Trek games, but due to a lawsuit very few copies were released making this one of the most expensive games on Ebay second hand.
Possibly Star Trek: Bridge Commander falls into this category also.

I would have to agree with the Starfleet Command series also. I was a fan of the oldschool pen and paper RPGs and strategy games. Starfleet Command was a very faithful interpretation of Starfleet Battles.

I would love to see Tomb Raider.
I still remember what a joy it was running around that world made of joined squares, with the worst control probably ever in a 3-D game, spelunking for artifacts.
The fact that the game is so dear to my heart DESPITE it's flaws is telling to me. What seperated TR from it's sequels was the focus on exploration, a minimalist soundtrack, and the low amount of fighting you had to do in the game.
I have always wished for a POP game with the same minimalist structure, and little to no fighting...Sands of Time almost did it...but not quite.

I see Kohan listed as by published by both Ubisoft and Strategy First. Either way, those games must be well within GOG's reach.

Wouldn't that one be in Activision's hands now? *shudder*

I can't honestly claim to have heard of it. But it does look interesting.
Star Trek licensed games have all kinds of legal problems anyway. If it was having legal problems before then I'd imagine that it's not about to make a phoenix-like return.
Activision had the license then. It now seems to rest with Atari. As do many desirable licenses. So any Star Trek games that Atari don't hold the rights to can't be sold.

OK, 'fess up. Who did you kill? :P

Dungeon Keeper 1 and 2.

My most wanted? Hm.
The Ultimas especially Underworld, Betrayal At Krondor, and well, em, Yendorian Tales.
Both Hexens, first Heretic, Infocom's text adventures, Legend Entertainment games [Gateway!], both Crusaders and so on.
Oh, and GOG making a special dev team that would MAKE good old games, every year or so a neat oldschool adventure game, or RPG [pre 'acrion' rpg, and pre-BG rpg], that would be supported for years, and years, with expansions coming out and making the game even bigger. And then i woke up..
Only if it's the Windows version [keeper95 of keepd3d], the DOS version had a sh..y AI, sadly, it's the only version that i can play nowdays, VMs dislike DK, and especially DK3D since it's DX6/7 gen.

I wish to see "D".
It's a surivival horror game. I never played it but I know it recieved some positive reviews in its time and it's imposible to find this game now.

Another great survival horror game, "Clock Tower":
[url=http://en.wikipedia.org/wiki/Clock_Tower:_The_First_Fear]http://en.wikipedia.org/wiki/Clock_Tower:_The_First_Fear[/url]
I heard it had a Windows 95 version but it's impossible to find again.

I have 4 most wanted:
American Mcgee's Alice
Because it's the best insane game I played for a long time. Psychonauts is really close to the madness.
Prince of Persia Warrior Within
We have SoT, WW may not be counted out as classic! I know with Ubisoft's DRM, but dammit, I want that game again with all the goodies 8D
System Shock 1&2
I am sick not being able to play SS1 on todays PC, also I hate to always get a pirated version of SS2 since it's nowhere in store and the ebay products are fucking expensive...
Max Payne 1&2
Both true classic, but are restricted on Steam due Germany. I really want to get some of their copies again. With goodies of course.

Nocturne
-Because I have no luck getting it to work with 3d acceleration on a modern card.
-Because I love the main charater.
-Because it's dark and wonderful.
-Because the use of shadows to boost atmosphere is the best i've seen in any game.

there are a bunch of games i wouldn't mind seeing here but my number one, my prayers have been answered, donate blood for game on GOG is Blade Runner by west wood
i know the game had lackluster reviews (i didn't see why, i kind of figured the reviewers werent happy with what they recived when they reached their hand under the table)
i thought the game was excellent. the mood, the sound, the music, and the look of the movie were all there. yet it wasn't a rehash of the movie plot.
the game had multiple endings depending on how you chose to play the game.
every one i lent the game to felt it was the best game they ever played.
which is why i dont think i have the game any more. must have never been returned to me by the last person i lent it to. i still have the box and the contents but no disks.
this is a game i belive would be worth slapping the GOG 9.99 price tag on.
in summary - the game was beutiful, the sound was excelent, the music was great, the plot was engrossing. if you liked the atmosphere and feel of the movie you will like this game.
edit: feel free to check out the game trailler on the internet to see what i am talking about

I have to say that Syndicate would be awesome to play again. That game was frustratingly fun and had a surprising depth for the sort of game it was.
The Carmageddon games (not 3, though) were time killing goodness.
Alpha Centauri and Alien Crossfire - YES!
I'd say Interstate 76, one of the greatest games ever made, but GOG beat me to it. I'm totally playing that right now. (well, obviously not red at this exact second)
Dungeon Keeper 1 and 2 - Huge fun.
Masters Of Orion 2 - I have it and it still works on XP, but you can't really buy it anymore and it is an exceptional game.
Several of the old Jane's flight sims would be sure to please.
