Kirby's Super Star Stacker
With the new English fan translation patch, of course. Never played the original Game Boy version but this game is pretty great. It's a puzzle game where you clear Star Blocks from the board by sandwiching them between these special Animal Friend blocks depicting Rick, Kine, and Coo from Kirby 2. I've almost beaten the Story Mode (Gryll is beyond frustrating though), and done all stages in normal difficulty of Round Clear. And wow...never before have I seen Kirby 3 get so much love. Kirby even wields the Love-Love Stick from that game! I've had some...major frustrations with the Story Mode, but that aside, I've really enjoyed this game so far and am looking forward to playing more!
It's fun in multiplayer, too. You can even select characters (even though they have absolutely no impact on the actual gameplay, it's still fun to watch the characters battle it out in the center of the screen while you're clearing Star Blocks from the grid).
