Kotor I is a classic. Sadly Kotor II I never could get past the first world.
The first world is a chore, no doubt about that. But the rest of the game is totally worth it. Be sure to install TSLRCM and give the game a second chance, you won’t regret it.
Is the app version smoother? I had a glitch where I could not complete the main story quest.
Don’t know. I’ve only ever played it on PC.
