Jedi kick back and take a coffee break.
It doesn't take much HDD space or even a decent video card (Heck, while I'm getting the last of my money for my new PC, I'm running it on a laptop with an ATI Radeon Xpress 1100 mobo chipset), it's just gotta have some power. Don't forget the RAM. And as a plus its online its absolutely free!!!!!
Cons: Short. It's been (I think) three years since SW:RC came out. I've been expecting an expansion or SW:RC II, just because it left a Halo 2-esque (unnecessary) cliffhanger. I won't spoil anything, but just expect a cliffhanger that Star Wars Battlefront II might be able to fill for you on Single Player
Other Thoughts: As mentioned before, expansion or sequel is needed.
Also, make sure to turn your squad vocals to max variety. The squad is quite talkative for a tactical FPS about commandos. As well if the game just wasn't enough for you and need more i suggest to get the books
