Oh my god! I am a HUGE dragon quest fan even though I haven't played all of them, I have played IV, V VI, VIII and IX! My favourites have to be VI and VIII! I wasn't too stuck on IX but I still finished it.
Still mad about VII (3DS version) and X not been released out of Japan, A shame because the Wii U could really use a MMO.
I hope I, II, and III are ported to the 3DS virtual console, Lufia GBC was released on VC a couple of days ago so there's still hope!
