Why does it remind of Sonic Adventure?
I’ll say it since no one else will, I wasn’t that impressed with Super Mario Odyssey. There, are you happy? Who the hell asked for Mario running around in a real world setting? It looks weird and reminds me of Sonic Adventure. A lot. Thankfully the entire game is not set in that environment. Release date is scheduled for Holiday 2017 but given Nintendo track record I expect it to be delayed several times before releasing.
