It's funny cause footvolley has always been popular, but I used to see more kids playing 2v2 football than footvolley before. Nowadays I see more people playing footvolley than 2v2 or 3v3 football and it's all over the place. I honestly loved playing 2v2 or 3v3 but it's hard to find people to play it, specially older people. I guess the lack of contact is its "selling point" over other games.
There's even a "simpler" more practical derivative called foottable or futemesa in some places where they use the shittiest plastic table to play it.
