Just unlocked the last game in Wario Ware, a process that involves getting an acceptable score on all 216 different microgames on the game grid. So after many months of twitching on the T or during "study breaks", my game menu has no gaps in it. I beat the world. (The two microgames that were hanging me up in the end were the noodle-making game (with the maze of pipes) and the bookmark game; I ended up "cheating" by pausing a lot in order to slow things down.)
Congrats to Nintendo once again for a clever little game cartridge. I look forward to the inevitable sequel!
