Like, right now? (besides TNM)

Personally I am playing Neverwinter nights 2: mask of the betrayer.

Primarily:

Guitar Hero: Metallica
FUEL
Dawn of War 2
Left 4 Dead

Occasionally:

Jagged Alliance 2
SWAT4
HAWX
Freespace 2

On backburner due to frustration, lack of interest, or technical issues:

Mirror's Edge
Far Cry 2
Fallout 3
Zeno Clash
Freedom Force

Half-Life 2
Garry's Mod
Codename: Gordon ( With Steam in online mode click this: steam://install/92 (Yes it is legal.))
Half-Life
Half-Life Opposing Force
Counter-Strike: Source
Garry's Mod 9

Those are the main games that I am playing as of yet.

TNM
STALKER Clear Sky
Obscure 1 and 2
Portal
Prey

That's interesting. Fallout 3 was running fine on my machine, but now it crashes all the time. God I hate bugs.

What I'm playing right now is:
Call Of Duty: World at War
Freedom Force Vs. The 3rd Reich
Railroad Tycoon 2.

What I would like to be doing is:
Make a surf map using blender and the FPS template, so far everything is going bad.

Football Manager 2009 (sooooo addictive)
Quake Live

If you patched it lately that might be a problem. Bethesda destroyed the game with the latest patch.

inFamous
Red Faction Guerrilla
Sims 3
Warhammer: DOW II
Littlebigplanet
Metal Gear Online
Killzone 2

Sadly my computer is not enough powerful to play any of those games listed here. Ok, there might be about 5 exceptions.

Games I play:

OpenArena(addictive multiplayer FPS game based on Quake 3)
NES
SNES
(yeah, that's right! screw boxes,stations and wiiwiis!)

Rarely:

World of Warcraft
Warcraft II & III

Cake in Winamp. Got the whole discography. I've only heard one of their songs before last night, or so I thought, but it turns out they made the Mission Hill theme. This is some good shit.

Oh, you mean games? Picross and Pic Pic on the DS (both numbers/grids/pixel art puzzle games), occasionally playing a single day of Rune Factory 2 before putting it down again.
Just beat T2X, gonna maybe look for a few good custom levels then just uninstall both Thief and T2.
UFO Alien Invasion, but I've become a lot less enthusiastic about it since I found out aliens can come out of nowhere and shoot down my completely undefended and unarmed troop transport jet. I can't even escort it with my attack jet, which itself is useless so far against UFOs, because that thing's max fuel range is half a continent and the troop transport needs to respond across the globe. So lame.
Trying to finish Gothic but I've been running into technical problems. Shiiiit. Gothic 2 runs fine, at least in demo-form. I'm so close to the end of Gothic, too, and all these problems just came out of nowhere.
Thinking of reinstalling Max Payne 1 in the very near future.

Hey, Gothics rule! Can't say much about the 3rd one although its not that bad. It still has the same old good gothic atmosphere. What I really liked about Gothic 2 was the combat system, it's challengin at first when you start the game but when you're nearing lvl 30 you can easliy take on a group of baddies, you get the feeling that you really ARE strong and thats the way how it's supposed to be. Not to mention the awesome atmosphere the 2nd part had, I remember the night when I was playing the mission where you have to go to valley of mines and look for the entrance to the castle, orcs all around camping.. torches everywhere, broken castle parts.. man thats some damn great atmosphere. I really had this feeling that "do I really have to go there?!". Anyway, when I finally found the entrance to the castle I didnt want to leave from there In my opinion, no other RPG is better than Gothic 1 or 2.
These games are totally masterpiece like Deus Ex.

Oh yeah, you probably know that the 4th part is coming out.. Called ArcaniA. From the looks of it, I have to say that I am really disappointed. Now you have this stupid minimap and quest tracker.. too many things changed from the previous versions.. thats not good.
Yeah I know it's being developed by different team now but still.. this is a shock for the fans... Plus, it will be available for consoles too. But thats not all no! There will be 2 different versions, European and US.. what fucking bullshit is that!

J0w000d wants money..

Piranha Bytes are also making another game, unrelated to Gothic, which the Idle Thumbs podcast claimed will have more console friendly features. :sigh:

I have unfinished savegames in Serious Sam: Second Encounter and Jericho. But I intent to start playing STALKER Clear Sky (bought it new but it never worked properly on Windows 7).

I'm in the same boat with Mirror's Edge.. it's frustrating for me! I hate when you have to do something only one way and if you don't you can't procede! Far Cry 2 I just got bored, no challenge and repetetive! Once I figured out the strategy I could shoot them all from my vehicle from very far away and pick them off as they charged me... meh bored.. Far Cry 1 was great, which leads me to think they screwed up royaly with FC2.

Two games that have given me endless frustration is the TR series. Tomb Raider Anniversary and Underworld I'm stuck at a different part at each... and it annoyed me so much I just left it. Tomb Raider Legend was really short and too quickly completed...

Crysis I left also when flying that stupid air ship thingy.. I just kept thinking stupid stupid stupid air ship... I'm not playing this anymore! All the stuff before the air ship thingy was great! The suit and weapons are cool.........

The Crysis VTOL pissed me off until I realised I was flying into the tornados - hadn't even noticed those before. Once I realised they were the problem, I was able to stay airborne and have fun.

I got stuck in Mirror's Edge at a completely ridiculous 3-part jump where I kept missing different parts of it over and over again 20 times in a row until I shouted at my monitor and gave up. I'm unlikely to go back to it.

Far Cry 2 was great, loved it all the time I played it, but it kept freezing for ~5 seconds every couple of minutes and crashing to desktop every 20-30 minutes. That was on XP. Then I installed Windows 7 and upgraded my RAM and my video card, and FC2 still crashed. So now I dunno - it's on backburner until I have the energy for another round of debugging or I find a hardware configuration that can run it reliably.

However, at the end of this month, Batman: Arkham Asylum and Call of Juarez 2: Bound in Blood will be released, so I know what I'll be playing most of July.
