ninja gaiden on very hard is always hard, at lesat when you fight bosses that you cant always see. i dont mind a challenge, and that game certainly had it, but sometimes my biggest opponent was the camera.
anway, combat was too easy in KOTOR, and i only played the game (once) on the hardest setting. Still, like people say, as long as a more challenging game doesnt involve simply increasing enemy hit points, then thats the way to go. Unfortunately, with KOTOR's combat system it would be a pain to make the game hard without resorting to just buffing up the enemies.
