Great game for history geeks
Keep in mind, the Assassin's Creed franchise is definitely the one that made me become a gamer. With a broad array of challenges, immersive gameplay and an intriguing storyline, I didn't think the AC series could get better.
Brotherhood takes the best elements of AC2 (advanced weapons and controls, renaissance Italy setting and storyline) and layers on social gaming elements in a seemless way.
I've already lost one weekend due to this game, and I'm sure to lose many more as more DLC becomes available. It's a great gift for any gamer who has a sense of history -- or any gamer without one.
