mainly what I see, as well.
We have a couple "free play" arcades here in Houston. They both have a few recent titles, mainly oldies. I try to make the trip out there a couple times a month but damn that 30 min drive. Only been to the game preserve though.
The one crappy thing about free play is, when you go to play a game, there is always some little kid that was nice enough to start a 4 player game for you. Kinda wish they would nix the door fee and just make the games 25 or 50 cents or something. They would definitely make more off me and I'd be happy to pay the extra cost. Also it seems like a maintenance nightmare for the owners. But hey... if their happy, I'm happy. For $15 bucks, I'll play a few 4p games.
I've never been to the places in dallas, I did go to the original pinballz in Austin. That place is awesome, I didn't have an issue paying $1 a game for the newer titles. I'd be spending a lot more money on location if there was something like that out here.
