Plus, as many 3DS games did back in the day, Rhythm Heaven Megamix has a multiplayer mode that supports multiple 3DS systems with only one cartridge. The game received a physical launch in Japan, but only came to the West digitally, meaning it's your last chance to pick up this outstanding game. If you're not familiar with the series, it's got all of the quirky weirdness you'd expect from the WarioWare series, as it's developed by the same team. Rhythm Heaven Megamix is an all-star collection of the best games from across Nintendo's wacky rhythm franchise. There are some outstanding games in this section, and some fun little nuggets of Nintendo history that superfans will want to pick up. You'll want to grab these games now, as there will be no other way to play them in the future, until Nintendo decides to rerelease them on newer hardware.
These are the big ones - the games that are only available digitally, and will disappear forever once the eShops close.
