Have you seen Sword Art Online? It appears to only be one season in length... it's about kids playing an MMO. I'm pretty impressed with the writing, and they write everything as if you already know all of the terminology, which is good, because you probably do. It's hilarious to see them using terms like HP, Exp, raid, level, MMO, RPG, all without the usual caveat explanation for the non-initiated.

Anyway. We're about 4 episodes in and like I said, the writing is pretty good, really.
