Skip Revelation and AC3. AC3 was garbage. I never played Revelations, but from what I hear it's not that big of a deal. Did I say AC3 was garbage? It was.
I don't know where you can catch up or if it even matters. AC3 was garbage so it's probably best to not know (don't actually take my word for that, I'm sure there's a way to catch up on a wiki somewhere if you do a google search).
From what I hear AC IV does have multiplayer and it sounds like it's the same. It wasn't a big deal on anyone's review I read of the game but what I did catch about it was if you're into that it's more of the same.
I have heard mixed things about the Vita game. Some people really liked it. I don't think it holds any bearing on the main games plot, though. Since this is only hear say, feel free to not care what I say about it.
He would chuck, he would, as much as he could, and chuck as much as a woodchuck would, If a woodchuck could chuck wood.
Love Danny but I'm not a fan of threads that don't intend to start a conversation. it's still technically youtube spam if you aren't adding anything of note or inciting a conversation. I mean if people wanted to discuss this they could on the gamespot website for over a week now..
