Thanks for the answers, sounds pretty good to me.
1) Is voice only enough? I don't have a webcam, so
As for the app, I guess I'll have to figure that one out.
2&3) I think I'll be able to figure the system out. The main reason I was wonderin about character creation on G+ is because I've never done it, so I would need help with it.
4) Aha, well, that should be interesting, I'm working on my own setting (very, very, very slowly) so I might bring something in from that to a character, depending on what I play of course.
I think that magic level is fine, as long as there are no shops for magic items or magic street lights and such I'm pretty good with it.
Also, have no friggin idea what an arcanist is, so
