(This is my first one,so don't butcher me please)

Trine - The puzzles were fantastic,the story blended in with the environment,and the platform style just blew me away. 10/10

Unreal Tournament III - It was OK,in a sense. Though 75% of the servers were just crammed with bots,and whoever wasn't either was a bad sport,or a hacker. 8.5/10

Evil Genius - I loved this game as well. Making corridors of flame to take down any intruders made my day. The tycoon similarity was somewhat large. It went far into the detail of how a stereotypical ( ) evil underground base would look,although I made it rather unusual,heh.
10/10

Overlord - Camera made me angry. The game was generally good,not my style though. Controlling minions was fun,and arming them was even better. 8.5/10

Trackmania United Forever - This game was amazing. Although unrealistic in every sense,it was fun to do a thousand meter jump after doing a triple-loop. The online community is amazing. 10/10

I agree with these

Overlord i have to say, i would have given it about a point lower. After I got the blue minions, i could not control them on the boss in their cave at ALL and lost all of my minions i had in that fight. I ragequit and deleted the game after that >.<

I wish I could play Trackmania, but alas, it shan't run on 32 bit Vista.

Evil Genius is far more like the Dungeon Keeper series. Which is a very good thing as that was ,bugs aside, an excellent game. I just wish they made DK3.
