Super Mario World
Donkey Kong Country 2: Diddys Kong Quest
And now for two personal picks.
Fire Emblem: Monsh no Nazo
: still one of the very best FE games in my opinion. Getting both a remake of the first game and a whole second game following up on it was amazing. Playing Book II of FE3 was one of the most captivating gaming experiences Ive ever had.
The Lost Vikings II
: Blizzard did more than Diablo/Warcraft/Starcraft. Going with the sequel, which I feel improved on the original. These games are great fun to play with another person: even though only one person will be at the controller, the nature of the games allows for you and whoever is with you to figure out the way forward together. I played these alone when I was younger, then again in the last few years with my now fiance, and I really recommend everyone give both Lost Vikings games a try with someone else right next to you. You wont regret it.
