Speaking of arcades... I was at Free Play Arlington last night.
They had a great selection of cabinets like TMNT Turtles Against Time, NBA Jam, Tekken Tag, Gauntlet, Killer Instinct, House of the Dead, and lots of pinball machines.
Also they had Super Street Fighter II but of course some basement dwellers were hogging it all up and didn't really let anybody else play it. I was there for 2 hours with friends and it was literally the same nerds that were there everytime I'd walk by the bar.
I wanted to complain to management about it but it was just super busy and it wasn't worth the trouble so eh. But hopefully they establish some kind of rule where you can't hog up the damn cabinet.
Most arcades typically operate on the honor system where the only rule is "don't be a dick when other people want to play". Gonna date myself a bit but when I was growing up people put quarters/tokens up on the machine to signify next on and it was almost universally acceptable.
Can't really do that at Round One, and I've never been to Free Play Arlington so I can't speak for it, but if you hang around the machine and make it known you want next, someone will usually jump off for you unless they're in the middle of a session. No excuse for behavior like that with a fighting game box though.
If it happens next time you're there definitely bring it up to management. That sort of behavior is pretty much universally frowned upon, but also try to make it known that you want next. It's easy to say "Well I didn't know" if no one speaks up.
