Not a stayer
Overall the game was an enjoyable experience in that the character movement and combat was fun. But the designers seemed somehow to think that this would be enough and you are left with quite a dry experience.
Coming back to combat. This was rather one-dimensional. I'm not questioning the realism as in swordfighting a quick first attack or counterattack is normally the only effective way to get a clean hit. Modelling things in this way however does not make for interesting gameplay. In general the square button is the AUTO-WIN button.
Also, I was not impressed by the frame-rate. Particularly once at the top of buildings, there is a lot of tearing and stutter.
It is a large interesting gameplay environment, but it seems like you never really get to do anything with it. Maybe they just tried to do too much.
