The game started out really abruptly. I thought for a moment I put in the wrong disc. Unlike other AC's, there wasn't the slow tutorial esque start to the game. It threw you in and basically felt you should know by now.
It really felt 'old hat' which can be stale, but is refreshing to know that a game still looks great and feels unique. Very little that made me dis like the game.
I really enjoyed this game, i wasn't expecting to after failing to finish 3, but it kept me entertained. The main protagonist, Edward, is far more appealing than the previous one. This game may be the buggiest game to date that i've played in the series, not going one memory without a notable glitch, but nothing a reload couldn't fix. Another personal issue with the game, more than half of the game is spent solely as a pirate, that's all i can say without spoiling it. I just wish you spent more time as an assassin.
Sidenote: the combat is undeniably harder than previous versions, the lack of a lock-on mechanic, in an attempt to simplify the fighting, really seemed to detract from the game's functionality. There are enough collectibles to keep you looking for hours, yet the reward for completing the list is almost nonexistant, and not worth your time. Ship Battles were unexpectedly one of my favorite aspects of this game, while maneuvering the large ships might seem annoying in some tight areas, out on the open sea targeting an unsuspecting high level ship filled me with the best kind of mischievous excitement. If you're a fan of the series and you're genuinely interested in the story, i'd say it wouldn't be a bad idea to rent it out.
I have been a fan of Assassins Creed since its debut and will always be a fan of it. While I did find some aspects of the game enjoyable such as being a pirate, dive puzzles, and ship battles and some other things.
Overall I find the game far too easy. Almost right out of the gate you can invest in upgrading your character's weapons and ships stats to the max. Feels like they hardly put any effort into the hand to hand weapon system. One thing that really bugs me is that they immediately give you the locations of almost all of the collectibles (by synchronizing a way point) making it feel like one big grindfest.
All in all I can't say this was my favorite installment of this game but it does has its pro's too and is worth playing.
