Yep, turtles vs. toads. ‘Toads is supposed to be harder. The speeder bike level in particular, go look it up, you’ve probably seen it anyway. Ninja Gaiden is pretty hard going, too.
I adore Kid Icarus but might hate it if I weren’t playing on an emulator with save states.

I only got a chance to play the “Volkmire’s Inferno” level once, but it actually gives you points the longer you just don’t die.

The NES game I’ve seen an inexplicable number of people play is that Back To The Future Part II & III game, made by AVGN’s enemy LJN and completely hated and dismissed by most people, but I’ve sure watched a lot of people play it over the years.
