KOTOR is jank, but I would say it’s entirely due to the controls. It acts like point-and-click even on controllers, where you have to use the D-pad to select the element and interact with it using the face buttons.
Also, the semi-pseudo-turn-based combat system doesn’t really totally hold up, I wish there was a way of smoothing it out.
There are higher resolution texture projects for both KOTOR 1 and 2, I think KOTOR 2 has it available natively with the Steam Workshop.
