If you don't have AC: Brotherhood, fucking get it.
The AC series are such a mindfuck. The story mode is captivating and there are SO many things to do within it. The online multiplayer is hella fun, but the servers suck dick (takes for fucking ever to find "Abstergo agents").
I really enjoyed that game and I advise anyone who are fans of the series to get it ASAP.
Also, I just recently obtained FFXIII, has anyone played it? What are your thoughts on it? I thought FFXII was brilliant for the PS2 and nearly completed the game 100%.
