Hi SCONIN! Welcome.
I had the LCD handheld of Snake's Revenge back in the 90s which I sold on eBay a few decades later after the Metal Gear franchise got big. I think that was the only Tiger handheld I had.
I absolutely agree with what you are saying about design limitations. By actually making a G&W-type game myself, I was pushed to think differently about art & gameplay design, which was really inspiring.
I've often felt there's a bit of a foot race between technology and creativity, with creativity lagging some time behind. Gunpei's concept of taking older technology and finding new creative possibilities with it really resonates with me, and I wish it were something that all designers learned about early on... not just for games, but architecture, science, etc.
Fostering creativity in this way would bring alot more joy as well as novel solutions to our problems, IMHO.
