Might want to add this new one:
KumaGames has from what is said over 150 episodic games. I think the client is a DRM thing, but shouldn't be an issue.

Cave Story is an awesome freeware Metroidvania for PC.

Bygfoot is a soccer management game runs natively on Linux, Windows executable is also available.
[url=http://www.sacredchao.net/~piman/angrydd/]AngryDD[/url] is a tetris-like puzzle game. The goal of the game is to build large gems by matching up colors, then break them, raining more gems down onto your opponent.
ASC (or Advanced Strategic Command) is a turn-based strategy game similar to the good-old Battle Isle series. Available for Windows and Linux.
Flight of the Amazon Queen is a point-and-click graphical adventure game utilizing the SCUMMVM engine.
glTron is a tron-like lightcycle game with a 3D view. You steer a futuristic bike, called lightcycle. Combat takes place in a rectangular arena. Your bike leaves a trail behind, which is like a wall. The goal is to force the other players to drive into a wall. The winner is the last player alive.
LinCity-NG is a city simulation game.
TORCS is a multiplatform car racing simulator. It runs on Linux, FreeBSD, MacOSX and Windows.
VDrift is another cross-platform driving simulation. This game is in the early stages of development but is already very playable.
Quake2XP is not a standalone game but a modification for Id's Quake 2.

I'm sure there are many of you out there that remember The Goonies. I was playing this the other day and couldn't remember if I saw it on the list here or not. Either I overlooked it or it's not here. So here is The Goonies 20th Anniversary Edition.

There is a Goonies video game...really. Is it ANY GOOD?

Not too shabby actually. Better GFX than the original Goonies II for NES, but it's not the same thing either. In this one you play as Slotch. Or however you spell his name. You go around like the original, and rescue the goonies by collecting key and such. There's powerups also. It also has a map editor for mods, but I don't think the editor is functional yet because I can't get it to work. It's definately worth a play or two though.

Strange Adventures in Infinite Space just became freeware.

Has anyone had any luck getting http://www.rocket-surgery.net/abuse/index.html]Abuse[/URL] to run under Vista 64? I've tried a few compatibility options, the exe just sits in active processes and doesn't do anything (except turn my Aeroglass off).

I don't have Vista, but if you can't get the windows source port to work, I think the original dos version runs okay in dosbox.
