Dad wouldn’t buy me an NES when I was a kid. My next door neighbor had one and we played Top Gun and legacy of the wizard. Got an NES 20 years ago and still have it though my game collection is pretty small. Also have an old crt to play it on. Still bust out SMB3 every once in awhile for the nostalgia.
A few years ago I went back to see if I could even put a dent in Legacy of the Wizard. I couldn’t, it’s just brutal.
I would say more than half of all NES games are insanely hard to beat. Way harder than modern games honestly.
