Yeah, it's also neat that you can stop a sorcerer from casting spells for a while by cutting off his beard.
I guess magic in fantasy kinda goes one of two routes, you have the aforementioned blue goo thing where magic is basically a resource and spells are generally scientific, this being more of a vidya thing although some (like Magicka) do avert it. And on the other hand you have magic as, well, magic. Varg seems to prefer the latter.
I have to admit I do personally prefer to former blue mana goo type with scientific magic since it feels to me like it allows more flexibility while keeping to established levels of power, although ultimately they're both pretty good.
