The gameplay here gets 5 stars, but I have to knock it down a couple pegs due to the save system. While there's lots of cool new "hacks" to explore, you're discouraged from taking any kind of chance whatsoever by the infuriating inability to save. There's nothing worse than getting far into the game and then having to start over from scratch with the same low-level crap to work your way up. If the save issue were fixed, this game would be perfect.
