I was immensely excited about PSU when we first got that flash animation, back in who-knows-when but after actually playing the game, I just finished PSU on my PS2 once and never came back to it.

I kept an eye on the games and expansions that followed but never played them.

Bottom line, though: What was the story in PSU? I mean, we get to play as Ethan who goes on adventures after joining the Guardians during the SEED invasion, then there're Illuminus shenanigans, and years later some girl goes to find new planets on a ship that looks like a cross between a bird and a magical ferris wheel ... that's it?
