Cool thread Dive, and alot of nice responses.
Hrm... let's see... as the moment I am playing...
1. Animal Crossing Wild World - I never thought a game with nothing to do could ever be this much fun. Twice, even! It's got a, online feature but I have yet to meet up with anyone yet. I understand the reasoning behind prepopulating your "friend's list" for safety reasons, but it really shuts down any sort of community that could have been awesome. Oh well, at least there are more fish and bugs and fossils and ...

2. Replaying Doom3 - Because sometimes you just need to blast the shit outta demons, you know? I actually really like this game and have no beef at all with the (lack of) lighting. Yeah, that darkness allows for some cheap shots, but the suspense it adds more than makes up for that.
3. I was trying to go thru the Silent Hill series but other things got in the way while I was playing. I finished SH1 about two months ago. I never owned a PS1 and I only got a PS2 kinda recently so I never played the original SH1 game until now. I have played thru SH2 twice since buying it years ago. Then, I made it about 1/2 way thru SH4 but other games popped up... Then, I started on SH3 about a month ago and then the same thing happened. ha!
4. Me and some friends get together once a week or so and shoot 'em up with Star Wars Battlefront on Xbox Live. Now, THAT is friggin fun. Even though that game is years old, it's still fun as hell. Especially when the game breaks down and we start shooting each other. HA! Nothing better than shooting a rocket at your friend's feet to make him fly thru the air!
5. Resident Evil DS - Same old RE that we all know and love. I have't actually had a chance to play it very much because it seems that recently I don't have as much time to dedicate to a game that needs an hour or more at each playtime (for lack of saves reasons).
Games recently finished -
1. Half Life 2 - After all the bad press about the loading slowness, I wasn't even sure that I wanted it, but I got it for x-mas. Man, this game was awesome! I loved the atmosphere! Fun, fun!
2. Fable: Lost Chapters - The extra bits (although, not much) were alot of fun. Nothing all that different but the snowey island and it's baddies were still really cool. I did find it really weird that I took down the "bosses" fairly easily though, and I hate boss battles too!
That's all I can think of for now. I know there are a few others, but I'm working and not thinking clearly.
