That seems ok, though I'd think something like "iscoinop" would be better than "isarcade". The "arcade" classification seems a bit odd in contrast with the others. That said, I'm wondering how stuff like gambling machines would work since that falls under coinop. I guess subcategories e.g. coinop/gambling; coinop/game; coinop/redemption might be a way to handle it, though it seems a bit messy.
