Solitare-my phone....at work(yeah, thats right, effin solitare!!!)

Caster is an indie game, and quite short, so I'd assume that the (4x) is the number of times he played through it.

As Wolfox said, it's the number of time I've beaten it. It's a fun game, but rather short (it can be beaten in ~1 hour).

I've just done Tales Of Monkey Island Episode 3: Lair Of The Leviathan
360, far too much (800 ms points each) and.... hmm.... maybe. If you don't have Fallout 3 at all wait a few weeks, there's a game of the year edition with all 5 addons coming in the middle of the month, may even be worth looking for a deal on ebay for it if you do own the base game
Mini-reviews of the DLC
Operation Anchorage - Meh. Too shooty and not RPGey enough (basically what most people complained about with the full game) but a bit of fun with a few interesting bits including the gauss rifle which is arguably the most important weapon for the DLC because criticals knock enemies down which can be the only thing that saves your life against the super baddies they add with broken steel. Its also a bit of a fun pisstake of FPS' in general
The Pitt - So-so. A bit too basic and mostly samey. Felt like it should be in the main game because it just didn't feel different. Anchorage and Lookout have significantly different scenery, broken steel has a pretty big airbase and mothership zeta is one enormous new area but the pitt didn't feel unique in any way. Also even if you aren't an achievement person, the fact they have a "Find all 100 bits of metal hidden in obscure places surrounded by annoying enemies" one will likely piss you off.
Point Lookout - The DLC starts to get good here, nice swampy locales and mutated hicks that look like an embodiment of stereotypes. Some fairly interesting and weird missions with some good 50s mad scientist schemes
Broken Steel - Big new airbase with lots of fighting and new guns including the tesla cannon(think a lascannon that uses a single electron charge pack round per shot and can kill most things in one shot) Adds 3 major new nasties, the super mutant overlord, the ghoul ravager and the albino radscorpion that seriously challenged my level 30 character equipped with insanely powerful alien guns. This is where the gauss rifle's knockdown was so damn useful, especially with the radscorpions, those fuckers are stupidly nasty.
Mothership Zeta - Pretty damn good. I know I'm biased as a scifi nut but it felt better and had good secondary characters and missions. Put some points into unarmed, you need to punch folk for a bit. Really nice ending boss fight like thing and some sweet outer space action. Keep all the alien epoxy you can, fixes weapons you don't get spares of.

Wow, thanks for laying it out for me. Those last three sound awesome! I love mutated hicks and anything related to space. I already have the game, but it's probably going to be cheaper/around the same price to just buy the GotY edition. That's really annoying.... Maybe I'll just pick up Mothership Zeta for now and play them in an episodic fashion.

The latest games that I finished was, Bioshock, Tomb Raider Anniversary, The Witcher and STALKER Clear Sky

Just finish Need for Speed : High Stake

Recently finished:
Darkest of Days - Good, average game with some neat ideas. Obviously low budget, but still fun to play.
FEAR 2: Reborn - Took like 45 minutes, not the best expansion... too short to even remember clearly, really.
Deus Ex: Invisible War - Not nearly as good as the original, but not nearly the horrible piece of crap many fans will tell you it is. A solid FPS/RPG hybrid with some neat ideas and story elements.

Ewwwwwwwww @ its shortness.
I liked the game, but the universal ammo really was an awful idea.
I preferred Deus Ex (Original).

Finished Bad Company (PS3). Short, but fun.

Dark Messiah: Might & Magic, Lost Planet Colonies, Dead Space, Fable: The Lost Chapters, Devil May Cry 4, Fallout (Dec. 08 so close enough :P), Mirror's Edge, Prince of Persia: The Sands of Time (Thanks to GOG for getting me back into this one!), The Graveyard, The Path, Street Fighter IV if you count arcade mode on hardest difficulty.
LPC was hard as balls at some points (course I had it on hard mode)..Sands of Time had that maddening sequence near the end...I ended up using someone elses save after about 20 times of falling to my death..rarrgh.

Finished it myself about 20 minutes ago.
Good game, although I'm slightly gutted I couldn't find all the riddles... only managed about 80% completion. I'm not one to bother going back into a game for 100% though.

I finished the following games:
1. Street Fighter 4 - unlocked all characters by beating Seth with all characters x2
2. Grand Theft Auto 4 - very long game but badly optimized for PC
3. FEAR 2 - not scary at all for me, it was more or less a snore fest
4. Fallout 3 vanilla version, can't get the expansions here thanks to GFWL x2
5. Medal of Honor Airborne - Unrealistic FPS for WW2
6. Brothers in Arms: Hell Highway
7. Warhammer 40k : Dawn of War 2 (singleplayer portion)
These are the game I can think off at the moment.

I'll also add: Shogo, Zeno Clash, I Have No Mouth And I Must Scream & Paraworld to my list.
EDIT: Machinarium.
