I've been playing Assassin's Creed Syndicate and the game is a mixture of horrible and good. There are so many genuinely good moments / aspects to the game such as the fantastic cutscenes and voice acting, the improvements to wall scaling / parkour made by the nifty hookshot, the great characters (especially the cameos by famous historical figures like Churchill, Dickens, etc...) and the design of London in general.
But the core game play is so unbelievably buggy, bloated, unpolished and at times.... just unfun. And it's weird to me because I'm on the train home from work and I can honestly say I can't wait to start playing when I get home.
I would say this game is not even as good as Unity which I gave a 2-5/5. That game at least had tremendously better graphics and the amazing puzzle side quests (Murder Mysteries and Nostradamus Riddles). But both games really suffered from bloat...
Ugh the combat in both games is just horrendous. The combat in any AC game seems ridiculously unfun.
