Clearly we need different Ratings Board-chans.
I don't think we do, these tend to be accurate quite a bit (with the exception of Earthbound on wii VC, which later appeared on wii-u VC)
and even if it came to PC, it would help the company quite a bit by boosting sales. Sure there'll be piracy, but remember the case with The Witcher 2? Tons of people bought that after deciding that they liked it upon playing their pirated copies.
Plus there'll be mods that'll actually improve the game drastically and dat silky smooth 60fps + 1080p native resolution + AA and such.
Somehow though I doubt it'll be very demanding which means you could probably run it on a medium-powered PC.
Everything's coming to PC these days and it's quite fantastic. Whether it be good or bad games, I appreciate all sorts of games coming to PC as long as it doesn't contain securom or uplay.
