A damn shame. KOTOR 1 & 2 are still, IMHO, one of the greatest Star Wars stories/experiences. I'd really love for something to revisit the time period.
Not a shame, imo. Any remake would ruin it by changing things, I'm glad this has happened as you are right that the games are the best star wars stories. They're also my favourite games in general, especially TSL.
No, I doubt it. Because they wouldn't keep it true to the originals. They'd change the characters and the story and cut out sections and add in new things and replace the combat and make it fundamentally not the same game anymore. Especially when it's not being made by the original makers.
Also, graphics aren't a selling point for me in games.
Even if the remake was worse in every way, why would it matter when you can still buy and play the originals without any issue? The KOTOR games are some of my favorite video games so I can understand not liking a remaking that (hypothetically) changes some things, but I don't know why it'd be a positive to not get a new version of it that might have gotten more people interested in the originals.
