I'm sorry but this still sounds like the same game to me. Why is it not called Beach 2-by-2-ball, or somethign similar, if the number of players makes it so very different? If I get a couple of my mates together and we bounce a ball over a net counting points when the ball hits the ground- how is what we're playing not (an informal game of) volleybal?

How is basketball different from indoor volleyball? They're both played indoors on a wooden floor court, both have two teams in opposition, playing simultaneously. Both have in bounds and out of bounds. Both have a ball. Both involve passing a ball. Both have scoring dictated by placement of the ball.

I mean, we can talk about things that make things similar all day, it doesn't make them the same thing. Is a hamburger a sandwich? Sometimes, the whole is greater than the parts, not everything is perfectly decomposable in life.

>> How is basketball different from indoor volleyball?

Because one is about putting the ball through a basket and the other is about bouncing it over a net?

>> Is a hamburger a sandwich?

Yes, actually.

But, a very special kind of sandwich.
