@noiob yeah! quite a few more, actually!
explorers of sky is probably the longest of the bunch, because it has like 20 hours of post-game added to it that goes into detail of the back-stories of characters

gates was the first game on 3ds, and has an animal-crossing like building mechanic

and super has the largest scope, and the most polished gameplay, shaking up a lot of things (it's also harder)

@noiob aaand oops, i'm totally acting like an ad right now (sorry!)
it's outright my favorite game series though--they have such good vibes!
