The winner of every difficulty comparison

Mega Man all of them, they were all brutal. There was one with the tails looking dude on the ps1 that was not too bad

I think Mega Man 2 is easy compared to many other games from that era. It’s one of the few NES games I’ve beaten without save states or cheats.

Battletoads on the other hand…

I've got it on my homebrew Wii. I think I can still beat it, but I don't think I've done it in years.
