I have been looking for a new game that is a little different to the vast range of first-person shooters I'm used to. Mass Effect seems to fit the bill. It looks excellent, but I've heard about a few problems with it, i.e. some fairly serious bugs and an inability to save your game except at particular points (a huge dealbreaker for me, since I get very tired of having to repeat myself in games). Have any of these problems been fixed with patches? How playable is the game now?
