Since both eshops of the 3DS and Wii U will shut down next year, I decided to make a thread compiling games that you and I recommend. I got some myself:
3DS:
Pokebank (duh)
Pokemon Gens 1 and 2 on the virtual console
Zelda Oracle games on the virtual console
Dedede’s Drum Dash Deluxe (stand-alone game that is basically an expanded version of a sub game in Kirby Triple Deluxe)
Kirby Fighters Deluxe (Also a stand-alone game that is an expanded version of a sub game in Kirby Triple Deluxe) (got a sequel on the switch, but it is worth checking out it’s sequel)
Team Kirby Clash Deluxe (stand-alone game that is an expanded version of a sub game in Kirby Planet Robobot) (it got itself a sequel as well on the switch)
Kirby’s Blowout Blast (another expanded Planet Robobot sub game, though it weirdly uses a different title than it’s original version (Kirby 3D Rumble), and it’s basically Kirby’s Dream Land but with simple (though ranked) 3D platforming that mainly serves as HAL dipping their toes into making a 3D Kirby (which they would do with Kirby and the Forgotten Land))
3D Classics Excitebike, Kid Icarus and Kirby’s Adventure (definitive versions of these 3 NES games)
Pokemon Battle Trozei (sequel to Pokemon Trozei on the DS, but now with gens 1-6)
Pokémon Dream Radar (gen 5 spin-off where you can use the 3DS camera to find certain Pokemon, including the therian forms of Tornadus, Thundurus, and Landorus, which you need to get the Reveal Glass in B2W2 (also the first appearance of Kukui’s future wife, Professor Burnet))
Dark Void Zero (DSiware game that was apparently a “long-lost” Capcom NES game (it’s not, but the fake history Capcom made of it was honestly pretty cute of them) (also available on Steam, but I’ve heard that apparently that version has some drm problems, so for a more authentic experience play it on the 3DS)
