@thelostsoul Good point.
We used to have a couple of arcade machines in the common room at Uni. They swapped them around every month or so.
I remember one time they had Robocop, and people used to stand next to the enemy guy that throws hand grenades and just shoot his hand grenades over and over again while the timer counted down. They knew how many seconds they had to have left in order to complete the level before they ran out of time.
I never worked out whether you got more points per shot hand grenade than you got for remaining time left, but presumably they thought it was worth their while.
Made for a pretty boring game to watch though!
