You can do much better things with five dollars. Buy yourself some marbles. Buy your five friends some gum. Or maybe you'd like a yo- yo? I honestly don't care if you throw your five dollars in the trash. Just don't buy this game.
Luckily, Family Table Tennis' low cost makes it easy to justify an impulse buy for those in quick and urgent need of a virtual ping pong tournament. Just make sure you bring at least one friend along, though, because the single-player modes will leave you bored in a hurry.
