No one will think less of the dev in question. If Fenyx even leads to a game that is half as good as BotW that's great.
I mean, yes I do think less of Ubisoft than Nintendo in this case since I respect + look up to innovation and new experiences. That said, I won't necessarily think less of the game if it's still an enjoyable time... it's just more like a night on with a random show on Netflix vs. a night out (rip movie theaters) to see a blockbuster, different expectations.
