Magnavox Odyssey. 1972.
I can still feel the sharp corners of the controller box.
It didn't have cartridges with the games on them, it had 6 cards that slid into the front slot, with contacts that would close different sets of circuits to make the console play different games.
@mistyksnow.bsky.socialReskeet a picture of the very first game you remember playing.
It was either this one or Q-bert, though I liked Mario a lot more so I'm going with this one.
