I have played every AC since it all began and in the beginning, this feels like AC that we know and love, but alas things take a quick turn for the worst. Yes, there are some points that are good. However, nothing that makes up the huge retrograde step this chapter takes.
Yes, Mirage feels like the original ACs... but after the 3 epic chapters of Origins, Odyssey, and Valhalla, that's not a good thing.
Yes, they emphasize being an assassin and stealth... but if that's your play style, then no big deal.
But the 2 biggest downfalls are the claustrophobic and utterly boring map. One city ( Baghdad) , some desert, and training area all set in a liner path you must take. And the uter lack of story interest.
This is without doubt the worst installment of AC in recent years if not of all time. Thankfully I have now finished it and uninstalled.
