AC2 pretty much improves upon everything the original game tried to do.

The parkour is leagues more fun than in the original, the story is full of charm and manages to find a sweet spot between more light hearted and serious stuff unlike a lot of ubisoft games and features some of the best and most memorable characters in the series.

It feels like a really fast paced game, there isn't much downtime where you just do useless quests. Throughout the game you consistently unlock new areas and abilities to keep the game fresh all the way to the end. Also there's some ridiculously fun missions like the one where you fly into the enemy base.

My only issue with this game really is the combat which yes is a bit better but still not perfect, it turns into smashing attack really fast, after a while I noticed that sometimes if you don't engage in the fight and you have allies fighting you can just go behind enemies and kill them as if you were playing stealthily and it's kinda cheesing the game but oh well it saved me some time so I won't complain too much, also the game is really easy 90% of the time, I don't think I ever bought an upgrade or new weapon or anything throughout my playthrough and still beat it no problem.

Honestly wanted to give it a 10 because even with the combats flaws, I still enjoyed it, but my god did the game fuck it up at the end, basically it doesn't let you do the last mission until you get all of these codex pages, there's around 30 in total and I only had half of em so I had to spend half an hour getting the rest, idk I never liked when games just tell you fuck off, come back when you collected all of this shit

Oh well, still an amazing game though, hell I'd say it's worth it for the story and parkour alone.
