I have no problem with yearly releases. Most of the games have been great, including Black Flag, the most recent. The only 2 "mediocre" (and I wouldn't go as far as to call them straight-up bad) were Relevations and 3. The rest are great, and I hope they continue making it yearly, so we can see as many new historical cities as possible.
