Play on the highest difficulty. It gets much more complicated later in the game, I assume after half an hour you haven't yet passed the tutorial on that space ship, which means you only have 1-2 skills. Later on you will have way more skills, and you will have a party. Combat does remain pretty slow, but it sure is interesting.
But anyway, KotOR is all about the story. You will get sucked in eventually, since the storyline owns.
