KotOR2 has already branching out in areas not a real CRPG. First off it is based on a rules system that already exists. A proper CRPG would be as close to this rules system as possible. Bioware already butchered it once with limiting character creation and totally revamping the force, wound/vitality, and combat system Now we have Obsidian raping it again with further character creation limitations, boosting max level to 30, and making the force powers even stronger than they should be.
All this crap has butchered the rules of the game. Hell if Bioware didn't want to use the blasted rules as is why the hell use them in the first place. Why the hell is Obsidian continuing the stupidity with making the game and the Jedi even more munchkiny.
A real CRPG is Fallout. KotOR 2 is not so I guess it really wouldn't matter if you add elements of Final Fantasy or Kingdom Hearts. It couldn't ruin it any more than it already has beem.
