I kind of feel a lot of 8 bit era games haven’t aged the best. But there are a few that I love. Of course smb3 is really outstanding. That game is timeless and really showed how well Nintendo can make games. While I may personally prefer smw, smb3 was in my eyes the first to perfect the side scrolling platformer.
Mother is another game from the era I enjoy a lot. It hasnt aged as well as smb3, but it’s still a fun game to look back on. I feel the game was a bit ahead of it’s time, and with a few gameplay changes I think it would still be worth playing for any jrpg fan today
