>>6420582AC4 was.... ok. It's certainly worth a look and I'd be lying if I said I didn't enjoy it. It tried a bunch of new things, some worked and some didn't.
for Answer on the other hand, seemed to expand on everything that DIDN'T work while losing the stuff that did. Quickboost mechanics made fights uninteresting, laserblades were sickeningly overpowered, the new parts looked bad when mixed and matched, multiplayer maps were 9 different deserts, and the centerpiece of the game, the Arms Forts, were disappointingly easy. It's single player was ok at best but it had the worst multiplayer so far in AC. I'd give AC4 aq try but avoid fA. The only good thing about it is White Glint, and you can just buy a model kit.
