Take a HARD look at your desktop ...

It's got to be Civilization IV, I may not play it daily or even monthly but once I go back to it it captures my imagination for weeks upon weeks.

Same here, though Serious Sam would make me think long and hard.

*High Five* to the DIII-on-desktop-I'm-from-the-future club, I'm in.

If he was REALLY from the future, he would be playing Diablo3 in a WinBox emulator on his NeuroDoze implant. Except his NeuroDoze went RROD and now they call him Corky.

no program icons on my desktop, only folders and files I'm messing with at teh moment.
With w7 you can just access everything from menu start so easily.

I think that AOE2:TC is the game I value the most, and the only one I played for years, a while after I stop playing it I always play it again.
Actual games are AC2 and crysis wars, but AC2 will end, and crysis wars will be killed by crysis 2.

Not 1..But if I have to choose 1 it has to be prototype

No games on my desktop, but I would probably pick SC2 at the moment.

Or the STEAM icon, if that counts

I have nothing on my desktop.

But I cannot live without Quake3/Quake Live

It's all or nothing for me.

Multiplayer games tend to give you the most hours and replay value. But I haven't played a significant amount of multiplayer in months. I get discouraged because I'm pretty bad compared with most people (since I don't play that much) and there are so many cheaters everywhere. I don't enjoy games that are too difficult so I basically avoid multiplayer.

Instead I play single player games, but most of those are good for 10-20 hours and then I'm done. I need a big variety. I can't think of a single SP game that is so much better than the rest that I'd rather play it than anything else.

So I think I'd go with Freecell.
