the problem with a lot of these new retro consoles is they don't scale well on new tv's. playing them on a modern tv is like having cateracts in your eyes. i'd much rather have a proper upscaled version with all the fancy stuff you can do on pc to make them playable. graphics are a huge part of it.
i couldn't play any of these old games. i'm not interested in them in the slightest. i went to a gaming convention a few years back and they had all the games there including new games and old. goldeneye was there as were most classics and honestly i couldn't play it after 30 seconds it just gave me awful thoughts about a game i loved. i was literally confused at how i played it for so long and so often. the controls felt awful, the graphics were so bad i cannot remember them being that bad. same goes for all old gen consoles. as soon as a new console comes out i can't play the old ones again. so i usually give them away to nearby childrens hospital including all the games, etc.
i know some people love them but i think they are cashing in on retro being in fashion. i bet most people play them for a week then they sit there gathering dust.
There are limiting factors for sure but I am still sure people would buy it. even a multi console that they could sell master system/mega drive/saturn games on. Potentially Dreamcast too.
