Can't get enough

Whenever I have a morning meeting in or around Boston, I leave my house exceptionally early to beat the traffic, then as an end result sitting in my car playing Solitaire for an hour before the meeting starts. So this week, I've been installing a couple different games to keep my occupied in that situation. The laptop isn't exactly a gaming rig though, so new games are out of the question.

I don't have a ton of hard drive space either so I can't install my whole library. Ironically though, the only games I'd want on there, are the ones I've already played the shit out of.

The games that made the cut:

Battlefield 2 - In greater Boston, it's not hard to find free WiFi. And there are very few multiplayer games out there better than BF2. In fact, I don't think I've played ANY 360 game online more than BF2. The game is a few years old, needs a ton of patches to run correctly, and still glitches a bit on Vista, but it's still a ton of fun.

The Sims 2 - Yes, another EA game. And arguably targeted at female gamers. But regardless of how many times I've played through this, it's so open-ended that I'll still keep going back to. I haven't picked up any of the really recent expansion packs but there's enough content in the basic game or the "university" pack to keep me busy for hours. But if I have 5 minutes free, I'll put somebody in an empty room without any doors and watch them lose their mind.

Half-Life 2 - Does it really need an explanation?

Dead Rising - It's not something I can install on my laptop, but it is one of those games that I can't get enough of. The game can be incredibly frustrating but nothing is more satisfying than mowing down hundreds of zombies with a car, lawnmover, chainsaw, park bench, or anything else you may find in a shopping mall.

City of Heroes - The game is very repetitive, which is why I even cancelled my subscription in the first place. But I keep on bringing her back into my life anyway - I met a lot of really good people playing the game, some of whom have also moved from the game to 2o2p, and some of whom are still playing.

I wouldn't exactly call this my "Top 5 List" but I play some of these games more than others that would make the top 5.

Do you have a similar game in mind? May be a few years old, may not be the highest rated game, but you still can't get enough?
