I'm guessing if they've all played the BG games as was reported, then they played Throne of Bhaal in which your characters get to pretty high freakin levels.
Specifically thinking about the HLA's and some of the crazy spells/abilities characters get past a certain threshold.
What makes me optimistic is the stated hours for game length. If they had said 40-50 hours like most RPG's, I'd worry. 100+ hours is a good start.
