I was a kid when Gameworks first opened at Arizona Mills and it was a magical place. There were some really great interactive games that blew my mind: A game where you're strapped in a seat and you can rise up to the second story of the building as you try to pop other people's hot air balloons, a motion-detecting combat game, a huge bank of race cars for a racing game.
It's no longer magical. It's best not to know these games used to exist, because Gameworks is now just a large, average arcade with a LOT of broken games.
My companion and I bought Groupons for all-day passes and ultimately it wasn't really worth it. It seemed like up to 1/3 of the games were broken and the most interactive games they had (aside from the shooting/racing games where you hold or get on something) were Rock Band-esque games and DDR. Old news. We played for a couple hours at best and then gave our passes to a parent and his kid. It seemed like they'd enjoy them more than we did.
I'll choose to remember Gameworks for what it was and not what it is.
