Nintendo has been very active with the Nintendo Switch Online + Expansion Pack retro libraries lately. Although it varies which retro library Nintendo updates, Nintendo’s schedule with new additions has reached a point where it is guaranteed to see at least one retro game added a month.
For example, Nintendo has announced that Ghouls ‘n Ghosts, Crusader of Centy, Landstalker and The Revenge of Shinobi are now available for Nintendo Switch Online + Expansion Pack members, via the SEGA Genesis/Mega Drive library. You can see their announcement tweet down below.

Landstalker is still to this day my most favourite action Rpg even more than Zeldas.
Yeah it was incredible 😊👍
👍🏻Man you are old! My respect for My Nintendo News site increased 10 times.

I… want to see Lost Vikings! NEVER got to beat that. Was stuck in the damn spaceship. The old Power Rangers game with Green Ranger & Goldar would be something, too. Wait… It was the Genesis I played these on, right? 😮
It’s great to play this game.
Not to sound ungrateful but where’s Mario Party 3 for the N64 library? It’s supposed to be added this year and we’re halfway through it now, and MP 1 and 2 have been available since October last year.
I agree, where is Mario Party 3 and Pokémon Stadium 2, the Nintendo company is being lazy by not putting it out, once I get Detective Pikachu returns and my other games, I’m stopping buying games from Nintendo completely, it’s now just a waste of time and money, it was fun while it lasted .
