I'd say definitely get the first one. While KOTOR 2 is a worthy successor, the original is a better game in many ways.

Although I think that KOTOR 2 was good, I liked the first KOTOR more.

Kotor 2 should be the best game i ever played but ..

for me the 2nd part has a deeper story, but there is only the main line

nothing like 1sd parts small moments that can make u to play it over and over again, as Forna sad ...

Get both
