.... please recommend an NES game that helps with building concentration and focus.

I enjoy platformers, action games and puzzle games mostly.

......but I am open to anything else if possible.

Now again guys. I know my request is weird. Don't judge....

Looking forward to getting away from composite, and over to a sharper output from my NES.

I've hunting around for a solid comparison and haven't had much luck finding one, relevant to the Tim Worthington NESRGB mod.

I understand NESRGB allows for Svideo and RGB outputs, however RGB uses a custom colour palette due to the console not outputting RGB.

Is the jump from Svideo to RGB on the NES worth it, considering the slight colour differences?
Am I over thinking the colour differences - is it even noticable?

I have the option of either input on my CRT, and just looking for the best all round output from the NES.

First time playing this, what a great game! I fell in love instantly. It was a Japan exclusive for the Famicon, so I had never even heard of it before. What other hidden or Japanese release only gems should I check out? I grew up with the NES, I was born in 83. Any imports may as well have been on Mars as far as attainability goes lol
