PC -I will increasingly have access to the majority of games ever made at the option to be played at the best possible spec. Free online, cheap games, any controller I want and of course in this theory world I cannot emulate almost every single console ever made at highest spec available, but I can use things like PS Now. I can stream it to a tablet, play it on a couch, and do 1000000 other things with it.
boxing myself in, since in this world I can't emulate,...SNES. all day every day. The gens past that the graphics will look considerably worse and worse for a lot of games where as.. SNES is mostly timeless..except for things like Star Fox. etc..anything "cutting edge".
