ive also heard of US gamers saying that Kotor II cleans thier car windows as well, even though the game code most obviously doesn't behave in such a fashion.
US gamers can definatly play through with a minimal amount of bugs, if lucky. But there are some "bugs" that are just there. +Def force powers for example. Definatly doesn't break the game, but still annoying.
This is similar to Morowind (original release) on the xbox. Playable, but with some unfixable bugs., some of which caused game to be unfinishable for some people on some plays.
They had longer to produce, but also a lot larger game.
