I used to cycle across town with my paper round wages to pump into the moving Outrun machine in Stonehaven arcade - 40p! Those days the arcades had way better games than the home experience. I'm sure that machine was set to hard as f**k, I never got past stage 3.
Used to love the one day in the Xmas holidays when the arcade owners opened all day with the games for free. Big queue for Outrun though.
