I have no evidence to back this up so treat it as you will.
KoToR 2, imho is a good game when you look at what they were trying to do but unfortunately because someone just wanted to cash in for the sequel (i truly hope the person who decided this got fired after the release) sure it had some annoying AI's but that is all i can remember.
So when steam re-released it on steam i was jumping with joy! I bought the game and downloaded the restoration mod, 6 hours later the game crashes and i'm like "wtf?" i start up again then 4 - 5 hours later it crashes again, so i thought "maybe it's the mod" i didn't uninstall the mod because it's only 4 - 6 hours in it crashes.
Then i reach Onderon... Oh dear God in heaven, save my soul from this crashing hell, for thou's power is the only power to save me. Unfortunately my prayers went unheard and i could then only play 2 - 20 minutes before it crashes. Enrage i blamed the mod, so i deleted the entire game to be sure (there's a .unin). So i redownload the game, i finally get passed where it crashes, i then realize i have to set the resolution, i save and try to quit to main menu.
Much to my massive despair, the game crashes again. Remove the mods, Skyrim never crashed this much or this frequent and neither did Gothic 3 god damnit. That's right, i just compared this to Gothic 3 and i swear this to whoever/whatever is sacred or dearly beloved to you: Gothic 3 never crashed this frequent! And neither did KoToR 2 when it first came out and it's not the mod that is causing this.
So what remains is: Did steam botch this somehow? I hear steam has it's own DOSBox for old games.
