I have to still get AC: Revelations as it's a series that I don't mind waiting for it to drop into the cheap bin or GotY version. Altair was the protagonist in the first game and he returns for a little in AC: Revelations but that's still not enough for me to recommend getting the first game.
I've heard too many up and down reviews of AC3 to really be excited about as it seems the writing is a bit darker, the main character is grumpy and morose so the fun seems to have exited and the gameplay mechanics more of the same & even worse if you believe some reviews vs. anything really innovating the series. They did add naval battles which most everyone did like though.
I'll wait for it to get a GotY release.
The best part of the whole series, at least for me is just running around the cool cities and getting Assassin-y on fools. haha.
