It's time to review every Steam game I have...one in sentence or less. Most of these I haven't even come close to finishing...some I haven't even started! IT'S UP TO YOU TO FIND OUT. Or not.
Audiosurf - 3/5
Fun diversion, not worth the asking price.
Braid - 4/5
Beautiful graphics, beautiful music, extremely creative puzzles.
Morrowind GotY - 4/5
When this came out it was a 5/5, but in terms of combat and quest tracking it has not aged well.
Fallout 3 - 4/5
Repetitive environment, weak story, terrible AI...still addicting.
Left 4 Dead - 5/5
Hours of cooperative zombie killing fun, but make sure you know the people you're playing with
Left 4 Dead 2 - 4/5
Technically better than the first one in every way, but not creative enough have me coming back to it again and again.
Mass Effect - 4/5
The above average (but not spectacular) story is made better by extremely high production values and a decent morality system, but the frustrating combat mechanics and abysmal squad AI keep this from being perfect.
Psychonauts - 4/5
Hilarious, fun, and creative, but poorly paced a mechanically frustrating.
STALKER: Shadow of Chernobyl - 3/5
With the 2009 mod this game is very atmospheric (in a terrifying way!) and could be incredibly fun if you can get past the insane difficulty.
The Secret of Monkey Island: Special Edition - 5/5
I HAVE TO GIVE THIS GAME A PERFECT SCORE it's really freaking hilarious and awesome...but I'm not very good at it...
Civilation IV + Expansions - 5/5
I don't know why I bought these games, there isn't enough time in the world for them.
Team Fortress 2 - 5/5
Best online shooter around.
Torchlight - 4/5
Worth the $5 I spent on it but the content is too sparse to warrant the full asking price.
Doom 3 - 1/5
Okay I'll be honest here I've played none of this.
Half Life 2 - 5/5
One of the best single player shooters ever made.
HL2: Episode 1 - 3/5
Meh.
HL2: Episode 2 - 4/5
A little more than meh, but still not perfect.
HL2: Lost Coast - 5/5
This is only a single area as opposed to an entire game, but it gets a perfect score for introducing developer commentary, a feature which was then used in both HL2 episodes and...portal? Maybe?
Portal - 5/5
YOU MUST PLAY THIS
Mirror's Edge - 2/5
Creative I guess, but frustrating to play...especially the TERRIBLE shooting portions.
Prey - 6/5
I've played none of this one either.
Rollercoaster Tycoon 3 - 3/5
It would get a lower score but user made mods really improve the packaged experience, but note that i've never played the actual management portion...I just like building stuff.
Rome: Total War - 4/5
A bit dated but still fun.
Knights of the Old Republic - 3/5
Sorry nerds, but neither the story, characters, or game play are really astonishing me.
Trine - 3/5
Trine is another title not worth the retail price because not only is it short, but really after the first couple levels you've seen all it has to offer.
