All of you probably don't own one or the other 7th or 8th gen consoles, perhaps not most of them. So on the consoles you don't own, which are the games you want to play the most, which you can't play on the console you already own? You can list any game that have already released or are announced. Mine are as follows.
Xbox 360:
1. Halo 3
2. Halo: Reach
3. Halo 4
Xbox One:
1. Forza Horizon 2
2. Halo: The Master Chief Collection
3. Halo 5: Guardians
4. Quantum Break
Wii U:
1. Bayonetta 2
2. Xenoblade Chronicles X
3. The Legend Of Zelda
