I'm so indecisive I get overwhelmed choosing between a handful of games. I'd just spend my time looking through that lot, maybe playing a few minutes of one or two, then quitting to the next one in case it's better.
Galaga, Joust, Tron, Dig Dug, Q*bert, Donkey Kong, 1942
i grew up in the 80's and we sure didn't spend our lunch money on actual food.
then i discovered pinball machines, where if you were good enough you could actually get free games. that's where i spend the bulk of my time in the late 80's.
lots of video game emulators available if you want to relive the glory days.
fast pace ms. pacman was my fave since i was good at it when little. I kept repeating the red board, then it seemed like a random mix of previous boards. Very daunting when you eat the power pellet and all the ghosts reverse directions but never turn
