>>11912974>Drill Dozer, BoktaiYou can download the rest, but please play these on actual cartridges because rumble and light sensor.
>Bit GenerationsA series of cool games which barely got any buzz. I like the racing one.
>Castlevania x3Play in release order. If you have already played the DS ones, CotM will feel weird but it actually owns.
>Chu Chu Rocket!Best puzzle game. You can also try "Mario vs Donkey Kong" which could've been any characters but is a fun game.
>Kuru Kuru KururinClassic very Japanese set of games. Also has a GameCube one.
>Golden SunBeautiful RPG. Has two games, which you can link up to sorta continue when you finish the first. Some whiners complain about dialogue, but I rave about the Lufia-like puzzles and personally enjoy story. Also love the battles more than any RPG.
>Mega Man Battle NetworkHas 6 freakin games. It ain't Megaman; it's a new genre of game. You explore pretty old school feeling digital 'dungeons', and get into random encounters. But the battles are very unique and in real time, using a deck of cards you choose. Give the first one a shot!
>Mega Man ZeroFour games! Tough as nails, cool upgrade mechanisms.
>Harvest MoonThese are the reason Harvest Moon survived into the modern era. Friends of Mineral Town revived the series, in my mind.
>Advance WarsFire Emblem except better, part of a long-running JP series. Sucks they didn't keep localizing the games after.
>Riviera, Sigma Star Saga, Yggdra UnionI own these, but have not played. They are sposta be pretty rad.
My go-to recommendation source, probably where I heard about all this. Also has other lists around their site:

There are also translations of various JP-only games to explore.
