I'll field some AC questions since I think me and MAF are the resident AC fanatics.
How's Asscreed 1 & 2 on PC again? I'm more curious about 1. I need to start playing this series.
Tech-wise they are awesome. Ass1 has INSANE textures on PC. Looks freaking gorgeous. They dropped that with Ass2 and on but it still looks very nice and they run great. Otoh the X360 versions look just "good" and run 30fps & the PS3 versions..................

we're talking about 15fps with shitty IQ.
As for the games themselves. Ass1 is TERRIBLE. It's solid at the start and it's pretty enough to run around climbing the cities, but it'll be a pain to finish it (see: MAF AssCreed replay thread).
Otoh, Assassin's Creed 2 is a wonderful action adventure game with a super entertaining story (and a good one in the MGS wacky videogame sense), lots of varied gameplay, and great cities to follow the narrative through. It's one of the most memorable AAA games this gen. If you do everything it's a good 25-30 hour game.
I haven't been able to get more than 4-5 hours into AC1 and AC2. Any reason to think Brotherhood would be any different?
No way unless you don't care about stories and just want gameplay. AssBro has good gameplay, even better than AC2; but there's only 1 city (Rome) and it unlocks veeeery slowly a piece at a time until the endgame. The story kind of sucks and is totally irrelevant in the scheme of things and the Desmond portions are pointless. I'm glad I played it because Rome was a cool location to explore, but the game was completely forgettable and I'll never replay it, just like I'll never replay AC1.
/fingers crossed Revelations is better!
