Original NES. Mario 1, 2, 3. Just about every 1st party game was legendary, but the sports games were great too. There have never been better arcade versions of their sports than Tecmo Bowl and Baseball Stars. Shit, there have been like zero real improvements ever made to the original formula of the launch title Golf. Then there was the amazing 3rd party support. Everything from Jaws to Jackal to Top Gun to Maniac Mansion, Dragon Quest, Final Fantasy, and on and on. Hell, it even has a couple of all time racers with Excitebike and RC Pro Am.
The hidden gems catalog for NES would be bigger than the catalog for like half of consoles out there.
No brainer. NES.
didn’t even mention startropics and that shit with the manual
