Yeah, I guess that's true...still, it shouldn't be that surprising to spend time on one in a Star Ocean game. (I guess we all can't play 'em all.)

*This is spoilered, and may ruin the entire series. You've been warned.*

(SPOILER)SO1- You live on it! And...go back in time.

SO2- You...teleport there. For no clear reason. Rena lives on it in the first place.

SOBS- They all meet there.

SO3- Crash land. Twice! xD

That's not to say they didn't all had funky plot-twists either.

SO1- Oh, you cured the disease. Now we need to go fight an evil superhuman on the planet Fargett. Tough luck!

SO2- Holy crap, your world got destroyed. And you have to fight ten super-powerful cyborgs. It's like ten Jies, with religious allusions! xD

SO3- It turns out the whole universe is really a simulation. And it's gotten 'too real', so it must be destroyed. As if superhuman cyborgs with religious allusions weren't enough, now you have to fight God. Go figure.
