I finished off Assassin's Creed IV: Black Flag the other day, and thoroughly enjoyed the game. Now I've move back to the PS3 to play Assassin's Creed: Rogues and saying I'm really annoyed would be putting it lightly.
I've gotten to the point in the game where it suggests I upgrade my ship before doing battle in a rather interesting mission. The whole boating thing has been running awfully smoothly until now. I've gone through every single Assassin's Creed game so far and never once have I been halted for more than 45 minutes between main story missions. But here I am in Rogue stuck at a point where I've taken all the forts in the easy and medium seas grinding my way through whatever ships don't completely annihilate me so that I might someday soon be capable of getting near the end of this ridiculous spike in difficulty the story has me stuck on.
Besides this annoyance, the game is good. Not great, not bad. Just good.
