It's not in poor taste to use a concept of his to make a game when it's impossible for him to make it cause he's dead. If anything, it's a nice tribute to him/his legacy.
Speaking of games, I'm so mad we're not getting game news until 2017

They better keep supplying BOTW videos until then. And they better take us off the plateau in future videos

I'm starting to think the other regions of the map are gonna be barren wastelands since we haven't seen most of them at all and the game comes out in 5 months.
