I'm pretty indifferent for this one, especially knowing we've already gotten Banjo. If we hadn't, I'd be pretty down.
I never played Minecraft and honestly never really got the appeal (being 25, I knew some people who liked it), but it is certainly a big enough game and deserves it. I'm just glad it wasn't a character from a series we already have well represented, especially Pokemon. Stage looks pretty strong, which is what I always expected would be the best part of a Minecraft character.
Probably will never play as Steve, but no way it is the most disappointing though considering Byleth exists.
