Starts off great but steadily loses quality. Halfway you realize that it's not a role playing game at all, because half the main missions require a combat build and have a single way to complete them. Going so far as to give enemies the ability to see through walls and ignore your invisibility so that your fully leveled stealth skills do nothing. So, the gameplay ranges from good to irredeemably atrocious. The only things that are consistently good are the writing and the characters.
