I seem to be one of the few people who actually likes the AC formula. Although I may be biased since I've bought all of them for under £10 individually so entered with lower expectations and/or didn't encounter buyer's remorse*.
So long as they don't cock it up like they did with Unity, chances are I'll buy it when given a massive discount.
*Except for AC3. Stopped playing slightly after the prologue since Connor is an abysmal character and it seemed to be tons of talking about literally ****-all except "Hey, Americans will know this guy from their history books!"
