We'll be discussing both more later on, but if you're curious, here are some quick notes.
NES Classic Edition
mini Sega Genesis
At first glance, the Sega console seems to be offering more, but also note that the "80 built-in games" includes 40 actual genesis title, plus 40 not-as-exciting arcade/puzzle games. Still, 40 is more than 30 and this can be expanded upon via an actual cartridge slot (plug-in model) for playing your old collection or via SD Card (handheld model), while the NES is locked in at 30 games.
