No, I never have played through KOTOR. I have it installed, even, but it sits on my hard drive and collects dust.

I should, I really should, but it came out during that awkward 2D -> 3D transition era, of 1995 to 2004, where the majority of games looked like ass. I frankly felt that 2D was grossly superior to 3D in games, visually, until 2005ish when Oblivion was released--then things changed for the better, and 3D looked good. We had a lot of awesome 2D art in games prior to 1995, even the 16 color stuff in the late 80s was better than some of the ugliness we saw in the late 90s.

That's my excuse, at least, for not playing through KOTOR. I do have a huge texture pack installed, which helps. The longest I've been able to play it, so far, is the first hour or so of the game.

I owe it to myself to give it another shot. Maybe after I beat Divinity Original Sin?
