All of these retro things are better in theory and once you actually sit down to play these archaic games you get bored after 2 hours and go looking for a PS4.
The other day I bought for 50 bucks a modded original Xbox that works as a normal Xbox but also has basically all the NES, SNES, and Genesis games ever made stored on it, plus some NeoGeo and like 30 N64 ones too.
I played Contra for like 15mins and got bored. Some of those still hold up tho, like PunchOut.
