The arcade is a separate area. It is not part of the club or lab--separate room, separate floor on all ships. The arcade is open to anyone of any age.
There are times when the Edge group does "Invade the Arcade." For that time, all the games are set to free play.
On the arcade card, the limit is whatever amount you have loaded onto the card. There is no way to limit a child's charging on their KTTW card--they either have charging or they don't. And there is NO reason that a kid needs charging to do anything in the programming.
Another thing we've heard of older kids doing is to convince a younger kid with charging to put money on the big kid's arcade card--yeah, not cool.
