If you want a good Space Opera table RPG, go with uncharted world. It is easy to learn, easy to play and is very fun.
It is a game where you'll have to be very creative about what you tell because the game is focused around storytelling and not mathematics ( if you look at pathfinder you'll find that a big part of it is mathematic).
I won't give too much details because I'll share everyone of my games with you so you'll be able to get an idea of what a game can look like.
