Sit down Star Wars was my addiction. Proper vector graphics CRT stuff.
And used to make a fair bit out of the fall machines, some of which went up to 10p, and I never put any money in myself. Just hang around and grab natural falls. Then checking for change in the reject slots of machines. Eventually would get chased out by security, and then head for another arcade where they had gambling machines and double up the money. Kicked out of that and there’d be another to try. Beauty of growing up by the seaside 😀
In later years though, Gauntlet was king of the arcade.
Most annoying game was Dragons Lair, again a later game, based on a laserdisc. Cost a fortune and you’d last about 10 seconds.
