@Sanichi: It's looking that way. I originally came into this game planning to main Valeria for character fan-ism (Suikoden), but I played Athero first and my tendency to love defensive classes took over. I'll most likely play him most and have her second-in-command.
@Rofl: OB usually removes restrictions on accounts that can get in. You should be able to register at any time before, during or after this period and get in. 'Tis why it is called "Open Beta."
I didn't make multiple accounts during CB, since I only intended to test a class or two and that would have been excessive anyway. But for OB, I'm preparing for the official release and at least want my names reserved in the event that there is no wipe, or the wipe just drops people to level 1 and removes all stuff acquired in-game.
Zidane (FFIX), Belcoot (Suikoden V), and Zelgadis (Slayers) will be on the secondary account. I've got enough on my hands with my primary account, which will house Athero (original name, my main), Valeria (Suikoden, my second-in-command), and Freya (FFIX).
