I wonder if the psychology of the Switch being a portable as well as a home console is helping these games sell more than other platforms (in addition to the current lack of massive competition, of course). People always scoff at indies being part of PS+ and Games with Gold because they bought their machines to play "AAA Games not indie crap". I've always been more comfortable with buying smaller / indie games on handhelds myself, and given the choice right now I'd always prefer to buy them on the Switch just because of the portability of it (and because I'm travelling more).
