If you're looking for something outside of the old republic universe you could try the force unleashed. It takes place between the two movie trilogies so it's a bit more stormtroopery than the old republic. It also has a sequel. Also I remember enjoying the Jedi Knight franchise, which started with Dark forces and ended with Jedi Academy (I think). And, even though its geared more towards kids, the Lego Star Wars video games are a lot of fun.
