I liked Assassin's Creed: Brotherhood but I wouldn't go near saying it's a great series. I didn't like the first two, but I am buying the last in the series. I'm a story geek and just curious as to how they're going to tie it all together.
And I really loved Half-Life. I played all the stupid cheesy spin offs too.
I've always liked the Myst series, including URU, but I've only ever met one other person who agreed or who even knew what URU was...
Any of those FPS games out now. (BF, MW, CoD, etc.) All my friends think they're God's gift to gaming but I find them extremely boring. (All my friends also find my favorite game - Morrowind - about as fun as paint drying.. so yeah...)
Baldur's Gate. I am obviously missing the gene needed to play multiple characters in 3rd person.
And I wanted to play the Gothic series, but the only disc I could find was some collection of all 3 of the first games and it didn't work. The first game never loaded past the first screen, the second game had the expansion that made it frustrating to the point of spending 10 hours just trying to survive walking 5 feet, and the 3rd wouldn't run.
