NFUs FTW. There is nothing like the challenge of having to think rationally.
Seriously though, I think people forget that the magic of
Star Wars isn't necessarily about the magic--though the Force is certainly what makes everything so unique and phenomenal. But being a Jedi can actually be decently restrictive, despite the fact that at first glance, they would seem more creative. And many Forcies get stuck in a rut, having to train just to one-up that other ridiculous Forcie guy.
Playing an NFU makes creativity essential. You can't beat a Forcie with an NFU if you're not inventive. Or maybe you don't even want to deal with Forcies. While
Wars is in the name, combat isn't everything. Imagination is what counts. I'm not saying FUs don't promote imagination, but you'll find your imagination is able to expand a lot more to surpass the NFU boundaries that FUs don't have. Forcies... can be lazy.
And personally, there's just something dreamy about being a spacer! I've always wanted to be a pilot, and an astronaut at that. Think of all the exploration! The galaxy has so much potential with NFUs.
