Hahaha, yes! Did you swap around or were you always the same turtle? I was always Raph, because he was my favourite but also his roll kick was the best!
Once we dropped into the arcade on the way home from something, and so I made my whole family play The Simpsons arcade game, with my mum playing Marge, dad playing Homer, etc, etc... it was the best... my parents had no idea what was going on, but I loved it so hard.
I think the magic of Ground Kontrol is that they're not trying to make money off the games at all... it's all about the drinks and the games are just the drawcard... whereas last time I went into a for realsies arcade it was all crazy expensive... hopefully your Retro is also rad.
