Emulators and browser games. I'm sorry--that's not very helpful. Oh, and maybe now's a good time to observe that Tux Racer is pretty crappy.

Neverwinter Nights has a native Linux version. I've never tried it, so I don't know how well it works, but it's out there.

Defcon is hella fun, and the Linux port works perfectly.

Thanks for the suggestion, deadcowdan, but I can't really play any online or networked games - I'm on dialup. I was under the impression that NWN is an online-only game, Wikipedia classifies it as a MMORPG. Can it be played offline, by a single player?

cmonkey: I tried the Defcon demo, but it really wasn't that captivating. Not a lot of depth, you know?

Wii and PS2 mostly.

On Linux I played NWN years ago. Most of the FPS games get ported rather quickly, especially from iD.

Oh, and NWN is definitely single playerable, it's more fun online with friends though.

NWN can be played stand alone.

A fair number of games can be played passably to well using Cedega, but that has a small monthly fee, and is "non-free" both in speech and in beer (I think). How much that bothers you, I don't know. It's one of those things I have been meaning to look into one of these days, but I still do my gaming on XP. Although once someone has a truly good DirectX-alike, that I can play games on without ripping out more than two thirds of my remaining hair, I will give Windows the kiss-off.

sure, King of Prontopia, Wine/Cedega games are ... fair game. Any suggestions for windows game that work in Wine? I'm looking for fun games that I can play for a bit and put down again, but that are still engaging.
