I'm on board for everything that isn't Heroes, so really looking forward to this event. Everything I've seen from Builders is pretty and great, looks like the kind of thing that can suck me in for hours, and more main series games/remasters/remakes/ports are always welcome. Love me some hours spent hunting metal.
Maybe I'm weird, but Dragon Quest doesn't really feel Dragon Quest-y without classic controls/controllers? I got the I, II, III, and IV iOS versions, but they don't "feel" as nice to play. Still have nice, working DS/PS/PS2 versions of V, VI, VII, VIII and IX. IX would be pretty great on phones if they kept the online/multiplayer aspects, now that I think about it. Pretty much the only series where I will go out of my way to own multiple working copies of functional games.
Definitely all in on VII and VIII for 3DS. So glad these are officially on the table. That's what I'm interested in seeing the most right now, and more XI details, though another Anniversary Collection would be very sweet. More Mori Mori would be grand (best spinoff so far, imo), and maybe putting the Monsters games on the localization potential after positive reactions to VII and VIII confirmation? No real speculation, just hopes and dreams!
