I must apologize for being gone so long, but, I'm back now!
So for a newb guide, I think 30+ minutes is WAY too much.
You could always try reading a guide, but some people prefer audio and some visuals to go along with that, so to each their own. The game is complicated anyways, 30 minutes is probably a little long, but irregardless I'm sure that's ample time to explain the game mechanics and whatnot.
Some games need a long tutorial to really learn properly. When I was learning EUiv I watched a ~4 hour tutorial on Youtube. The length may be a turnoff to some people, but others, such as myself, appreciate the detail.
