I'm with Bif. Although not quite totally unplayable it is absolutely bug-ridden. That's my, and from the number of posts on the Technical Problems board MANY other peoples, reality.
When I can play it I really like the game. But man, the bugs are killing me. I lost at least an hour again last night when a save game became corrupted and wouldn't load. Then, I reloaded the one previous to it thinking it would have to be ok (silly me) and then about 1 minute into playing that save game, no matter what I did, it would crash to the desk top. I had to go back 2 save games before I could make progress again.
The game was obviously rushed out and then so were the patches. I appreciate the fact they are patching it as fast as they can but when the patches cause as many problems as they fix is it really worth it?
To anyone who thinks this is the "norm" for a game go play knights of the old republic. Not only is it an awsome game but I played through it twice without a single issue.
