X-game

X-game is a shop,
which sells skating equipments,
and clothes for skaters.
Only skaters buy those clothes.
so,
X-game is NOT a game.

Skating, however, is a game.
You can buy equipments and learn it yourself.
or you can ask the salesmen in X-game shops.
because usually those people are skaters.
Those in Causeway Bay are even experts.

the most important point is that:
you'll need a skateboard to play this game.
and, the cheapest one needs $800,
for the board only.
not to mention the learning fees,
and the wheels,
and to put them together you'll need money.
