Update another collection has been released digitally recently.This wounderboy anniversary collection is suppose to have them all.It also will get a japanese physical release later on as well.Nice idea but no Monster Lair? The first and Monster Lair are my favs, followed by Monster Land and maybe III but I really prefer the classic fast-paced platformer style over the RPG-ish stuff.
Gotta skip this one, already have them all in various versions.
