Now this is professional gaming. Professional gaming before multiplayer games existed. A day when competition meant racking up points and then comparing your score with someone else.
This is recognized as the finals of the first "Video Game World Championship", whatever that means. Twin Galaxies hosted a tournament with 19 people recognized as top players competing in 5 popular games of the time (Frogger, Millipede, Joust, Super Pac-Man, and Donkey Kong, Jr). These final 3 competed on TV for that sick bling you see at the end.
Back then being a 'top video game player' meant you had to be good at any number of games, and appropriately the competition (both the qualifier and finals) is spread across several different skillsets.
Even neater, this kicked off the Video Game Masters Tournament. Twin Galaxies assembled a 'US National Video Game Team' which was 5 players (recognized by TG as being the best) that were paid to travel around the country in a bus and play games in arcades in 8 major cities in the states. They talk about the experience in the documentary Chasing Ghosts. Walter Day claims his players were never beat during their tour.
This is the real old school.
