I was a complete DDR nut! In my stretch of working in Spain, I used to go round the corner from my apartment to the local bowling alley and put 15 to 20€ into the machine once a week! :D
After my uni days, I was looking forward to returning to my home town as a Namco Wonderpark wasn't too far away and they had the EuroMix2 cab... unfortunately I returned to find they'd closed it and opened more restaurants in the space. :(
They also used to have the Ridge Racer with real sized car and and motion version of WipEout.
