Team Fortress 2. A brilliant classic that's still a hell of a lot of fun for me to play.
[17:45:39] Wolfs Ghost (Murphy): Tom, you have problems. Go kill yourself.

I've never played Deus Ex, but from that, I can guess that No One Lives Forever/No One Lives Forever 2 might be to your liking. Fallout: New Vegas might also be something that floats your boat.
In other genres, Medieval II: Total War keeps me occupied for weeks at a time when I play a campaign for a nation I haven't played a campaign for yet. Recently, I've finished a campaign as Denmark (my favorite military) and have started one as the Byzantine Empire. This has taken me the course of a week and a half of playing 2-3 hours a day average. Very time consuming and good game.
Morrowind is very good as well. The same principles from Medieval II: Total War applies to Morrowind. I've played the game about 100 times, and I still have not finished the main storyline because I have gotten sidetracked with other ideas. I got really close on my last playthrough; I'll do it eventually.
[8:32:45 PM] Dusty Lens: Oh no, let me get that. Hello? Oh it's my grandma. She says to be roleplay.

I'm thinking of getting into a bit of Obliv as my "game I can't wait to play after school". But one of my all time favorites would have to be Star Wars: Knights of the Old Republic. Played it back in primary school- still love it.
