Super Mario World is my favorite of those listed also liked Act Raiser a lot. Castle of Illusion Starring Mickey Mouse was probably the best Genesis/Mega Drive game released in 1990. Michael Jackson's Moonwalker was also pretty good but the arcade version was a lot better and Columns and Ghostbusters where also pretty good Genesis games. Final Fantasy 3 was good but I think the best NES game released in 1990 was either Dragon Quest IV or Dr Mario.

That is kinda neat - I'm turning 30 next year.

1990 is one of my favorite years for many reasons

This cool gem is also turning 30 this year:

And this masterpiece as well

I'm turning 30 in January 2020. :)

Y'all forgot the best game of 1990

Better than Mario.

Also, uh ...

Pit-Fighter was only good in the arcades all the home version where sup par.

I’m turning 38 in 2020 :(

Fire Emblem was released in 1990, so that's a game and a franchise turning 30 next year.

Phantasy Star 3 turns 30 in 2020 and although it's the black sheep of the traditional games, I still really enjoy it.

SaGa 2 (also known as Final Fantasy Legend II) also turns 30 in 2020, in fact the SaGa series itself just turned 30 on the 15th.

And an old childhood favourite of mine, Nintendo World Cup was also released in 1990.
