Already a big thread on this: http://www.killermovies.com/forums/f6/t306665.html
There were some big mistakes at the end of KOTOR though. I've done the game as often as not on darkside and lightside. The thing that bothered me at the end (this is gonig to be a spoiler, but well, it bothers me) is that if you let bastila go on the Star forge planet, you automactically go to lightside till the end of the game. It doesn't matter if you kill her later on the star forge.... she's still there at the ending and you can't be a sith lord, ur stuck as a republic hero.
so that should be changed.
Can't wait for KOTOR 2. I'm very glad that we can't go to tatooine in this one. Don't get me wrong, it's a cool planet.... we've just seen it over and over again for the last 30 years (star wars movies included) and it's time for a new leaf.
The second ones great here are some things Ive noticed that make the game better
Its alot easier to get light side points thoughs of you who are like me are know what I mean. In KOTOR 1 I would all this stuff and never got any. This game the chances are equal.
Another is the crates buckets, and remains all tell you when here empty.
thoughs are little thing that make me happy over all it is a big improvement on a great game. Like more force powers moves weapons. The questions your asked in the beginning make me wonder how many different versions there are
