Hy, what's the different between your seperates sports game and this? And what happen, when we own any of these? Or will it replace these 3?

Can't find any button to close the game on PC, anyone found it?

Are there any reasons to own the other individual games if you've bought this? Are there any differences?

I am literally pressing the every key of the keyboard but still now passing that screen. In other games (SSB or STB) it works but in Volley it doesnt please help me.

I use keyboard to play this game,and I can not find the key"A","B","X","Y". In football game I can use Esc and Enter,but in volleyball they are useless.
