I personally have almost zero experience with this generation, though I realize it’s historic value. So many great game franchise originated here: Super Mario, Metroid, Final Fantasy, Castlevania, Zelda, Metal Gear, Mega Man, Mother…
I’ll give a shout-out to Mike Tyson’s Punch-Out!!, which I got to know by watching a YouTube video on the world record history for this game. I then played some of it myself on my Switch and was actually quite impressed with the almost puzzle like gameplay!
I also played Super Mario Bros. While I respect it for being the first, I thought it was quite ridiculous at times (the way to progress in the final world was so stupid).
