*Does anime fall.*
I should have expected that question from you.....
**Spoilers**
Yes, you get Endrance in your team, but it's not until Vol. 2.
Just about everyone you ever see in the game, becomes a party member at one point or another.
Though, characters can't get married in this game, man.
There's a news thing on it later on, but they can't get married as far as I can remember.
The item restriction you get used to. It's really not that bad except early on or when fighting a boss.
Oh, and a HUGE reccomendation. ALWAYS finish the game 100% before going on to the next volume. It will pay off in MAJOR amounts if you do.
PKers you'l get used to and you'll come to love killing them. There's even a sidequest to kill them and you get pretty sweet items and equipment from the bounty hunter questkeeper.
And the biggest thing about battles (only applies to the first two volumes):
As long as you're within three levels of the enemy's level, you can win (i.e. if my Haseo is level 15, I can kill something level 18, but with a lot of trouble, whereas it would be impossible to kill something past level 19 until I get another levelup).
This is especially important for storyline bosses and when choosing an area to train in.
Oh and trust me, you'll be glad you got G.U. first. From what I've heard, people prefer G.U. over the original series.
