The good: Sharp graphics Smooth animation Good story (assassin) Minimal cut scenes Health regenerates automatically Running across rooftops is fun The bad: Bad story (memory extraction) Random fight outcomes. There's no skill involved when fighting. You just keep clicking the attack button and hopefully you win. Frequent freezing until you update the exe (hex editor required). Autosave not frequent enough and no manual save. Respawning bad guys and no reward for kills. A lot of time wasted clearing out areas. I stopped playing once I realized this.
On a good note, you never die; You just respawn. It's annoying how the bad guys keep coming while you're trying to figure out a puzzle. Some of the puzzles can be frustrating. Plan on a lot of googling for answers. Fighting is more random than skill. The mechanics can be frustrating when trying to pick and use objects. XBox controller is supported but you need to set it at the start of the game. No inverted look.
