Good idea for a thread.
Right now I'm playing Thief 2. It's a first person stealth game, in which objective is to still varius amounts of loot and usually be a general nuisance to your arch-enemies. Sabotage rocks. The fun part of the Thief series is that they have a thriving fan community and a crapload of fan mission/mods released ever since the editors came out. We're talking about 5 years here. And about 600 missions, who sometimes even outgun the originals. Anyway, The main reason for playing Thief 2 right now, is that I was chosen to test a beta version of a certain long-awaited fan mission campaign. We(the test team) have our own forums. Feels damn great, considering that only 11 got to the first test phase.
The second game I'm playing is Clive Barker's Undying, a FPS from the year 2001, were you control a paranormal researcher and adventurer. The quest is to help his old war buddy from the first WW, whose family were once cursed by a strange enchantment. So, our hero travels of to the Covenant family mansion to help his old friend. And to fend armies of different kinds of enemies, when the sh!t hits the fan. Basically, it was his friend's, Jeremiah Covenant's, fault that the curse was unleashed, and the long-dead brothers and sisters aren't too happy about that. Add a big handful of lovecraftian influences, boil it in celtic atmosphere and allow the player to use one fo the most asskicking weapons in the history of PC gaming, and you have Undying.
I've also started playing Hitman 2: Silent Assassin, one of the best games I've ever bought, but I'm stuck in the last Japan mission. On the other hand, I've managed to spoil myself of some of the game's plot already, so I don't know if playing is worth the effort anymore. Fun game, one of the more intelligent ones out there.
