Rhythm Heaven.
I knew of the series for a while, but when I tried emulating Fever on Dolphin the delay was too much and I gave up on Tambourine. Some years later, I decided to try Fever again on my Wii U, and that time I managed to get through the entire game, and truly fell in love with the series. Afterwards, I played Silver (injected GBA VC on my 3DS), RHDS (Twilight), and Megamix.
I'm super close to perfecting Megamix. I can't even get all the superbs on RHDS, and I don't really have the motivation to. Silver I might return to perfect, since I perfected about half the games. Fever I might try to perfect just for Endless Remix.
