Still, it all gives a new meaning to "this little piggy went to market"...
So I went ahead and bought Minecraft on Switch. Played a bit but it'll be some time before I can weigh in on how it compares to DQB2.
Well... except for one thing where DQB2 is clearly better: the slimes. Probably not controversial to say Dragon Quest slimes are cute and Minecraft slimes... aren't.
EDIT: Someone recommended Terraria, which... well I'm kinda tempted but I'm not sure how I would like it. SomeCallMeJohnny said he couldn't get used to playing it with a controller... and he was using the more 2D-friendly PS4 controller, whereas I would be using the Switch joycons (I don't have an alternative controller yet so... yeah).
That said, I am interested but more because of the horror elements than as a building game--in the latter regard, I dunno, it may be kinda cool but I think I might feel constrained unless I was literally making a game.
Which on that note, Dragon Quest Builders sometimes makes me wish I could use it as an interface to make actual RPGs. Someone should suggest that idea to a budding programmer.
