Seeing the Move or Die QL made me realize just how overcrowded the couch multiplayer genre is. There might not be a more oversaturated genre now. You have the Sports Friends stuff, IDARB, Towerfall, Samurai Gun, Gang Beasts, the two games Iron Galaxy is publishing, Duck Game, Capsule Force, Speed Runners, Mount Your Friends, Nidhogg, Ultimate Chicken Horse and those are just the ones I can remember off the top of my head. In addition, you have the old standards like Smash Bros, Wind Jammers, Tetris Battle Gaiden, Sanrio World Smash Ball (In my heart), etc. If you're looking for a game to play with your friends, you probably have one by now. Even if you have good ideas, that space must be near impossible to enter as an indie.
The Fire Emblem Opera has existed as a marketing tool long before #FE. It was even in Smash Bros. It's really dumb, but it's supposed to be.
Particularly that version in #FE >_>
