Sonic and Mario are friends now.

For the uninitiated, Ghouls ‘n Ghosts is a tough-as-nails platformer that still gives nightmares to adults of a certain age. The Rise of Shinobi is a serviceable entry in the OG ninja-simulation franchise. Landstalker is a cult favorite action RPG with an isometric view and Crusader of Centy is a well-reviewed, yet relatively obscure, Zelda clone. Crusader of Centy is tough to find, with physical copies selling for thousands of dollars, so this is a boon for retro gaming enthusiasts. Here’s a video of all four games in action, so you can decide if you want to plunk down $50 for a yearly NSO Expansion Pack subscription.

As a note, these games are only available with a $50-yearly Expansion Pack subscription, though that also gets you access to N64 and Game Boy Advance titles. If you just want to play from a library of NES, SNES and Game Boy releases, go with the cheaper standard NSO subscription of $20 each year. Nintendo isn’t exactly speedy with these releases, with game drops around once a month, so before handing over your debit card information.
