One thing I liked with Kotor 1 were all the different planets you travelled to. I found it very compelling to see a variarity of places during my time as a lightsaberwielding force user. The idea of visiting various planets is very smart and in my case enjoyable. Naturally Kotor 2 had quite a few planets which you could visit, but I wanted more of them, more places to visit.
As a final remark on the muched hoped for Kotor 3, I would like to see a better ending this time, but I can understand the developers. There is always a clock ticking in the background, a deadline. It is only a "small" thing to correct. Kotor1 and 2 really are two super games, no arguements from me and keep up the good work!
