Ninja Turtles.
A staple of my childhood.
I had the toys, watched the cartoons, collected the comics - anything I could get my hands on.
I've spent many an hour and buckets of quarters playing the arcade games (I WILL get my hands on one).
I've played the games on a few systems - but not my PS4, so I fired it up and downloaded Shredders Revenge - it's pretty cheap, and free on PS+ if you have it!
