I lost interest in the series after AC II.
The original was fresh, somewhat ground breaking, while the second didn't quite reach those heights, but was a solid game.
Everything that has come after that has killed the series.
AC III was supposed to change that, but I thought it was the worst entry in the series with a boring character you just didn't care about.
While this new game looks promising, the quick turn-around worries me to no end.
If they want this to be the pirate game we didn't know we wanted, why not create a new IP?
Eventually AC will end up like the Resident Evil series, out of ideas and collecting dust in the bargain bin.
That is unless Ubisoft take a step back from the series, go back to something like Prince of Persia, and give it time to reinvent the AC series.
