SPEEN!
That's true for adventure games for sure. Hell I was stuck on a game for over two years before I finally figured out the solution. It was quite the feeling of accomplishment. It would have been 2 minutes if the internet was around back then.
But the term "NES Hard" exists for a reason. Some of those side scrolling action games were damn near impossible. Today's games with their multiple save points and check points just don't compare.
Just beating some of those games is impressive.
Speedrunning them is even more impressive. I couldn't beat Punch Out on my own, and some people do it blindfolded.
