Wait, there's a Ghosts 'n Goblins MMO?
Yes, there is -- but it's being developed by Seed9 for Korea. Much like Mega Man Universe (which we will be getting, thank goodness), Ghosts 'n Goblins Online retains its side-scrolling roots. I don't know that anyone ever thought it wouldn't, but there you go.
While I'm not so sure I would want to pony up any sort of fees associated with the "Online" part of the title, I would most certainly want to give this a shot if it were to leave Korea in one form or another. That'll probably never happen, though. Bummer.
