Yars Revenge - went off to college and found a guy in the dorm with a 2600 in good condition. We started having Yars Revenge marathons.
River Raid We got this the first or second Christmas after my family moved from where I was born. I remember my dad sitting down and asking if he could give it a go and then watching raptured as he proceeded to play it for a couple of hours. He wasn’t a big video game guy (he loved Pinball, though), but for some reason this captured his attention, if only for a little while.
Adventure - Played and beaten a zillion times. Young me was so fascinated by this game and yet couldn’t have anticipated what was to come.
Megamania - a fun Space Invaders inspired shooter. Each stage of aliens had different patterns.
Indiana Jones - ok so the movie didn’t feature a spider. And it had weird bits. But I loved it just the same.
