That was a joke.
Seriously, the force is not the problem. For starters it depends on what force powers you choose. In K1, even powers like force storm were not as powerful as to kill an entire room of enemies, especially on the end levels. K2's problem was that it was much easier, even without the force. My weapon master could take out an enemy with one or two hits with his lightsaber, even toward the end. The force is not the problem, finding the right balance is. And as I said, the force is part of KOTOR, so it belongs there.
I do agree with you on them not making K2, but for different reasons. Reason #1: K1 didn't even need a sequel.
