^ .....Mate....spoilers much? Some of us, like yours truly, haven't finished AC3 yet. Please remove the spoiler or put it in small tags so it doesn't happen to anyone else.
And I disagree with your sentiment about the series too. I don't mind a constant stream of new titles, myself. To this point, I actually can't say they've been milking it by any means. Each console entry has been great, moving the story along properly and attempting to polish the gameplay further. I mean, would we have complained if something like Shenmue actually got all of its chapters released on a steady basis over the course of 5-10 games, just because it ends up being a large amount of games? If you like Assassin's Creed at all, then the sheer amount of content they've created for the series ought to be seen as a blessing, not a detriment. As long as it's continuously good, I don't mind at all.
