Just because it is accepted doesn't mean its legal.. Is it worth the risk that one day someone panics and just wants to be sure? I don't think so.
But yes I will echo everyone else. Don't waste your money. Be patient. Go out to real games, try renting to see what you like, then once you save up and get AV'd, buy something that is worth your money. While $300 to $500 isn't twice as much money, its like 20x the quality of product you will get.
And one more time I will say... DON'T play in places like that! Just because you've been doing it and getting away with it doesn't mean its ok! One day you will regret it.
I love freedom and consequently America
