Ultima Online. This was, without a doubt, the best MMORPG ever! Its complexity and utter ruthlessness (Pre-Ren, anyway) have never been matched. It really was like living a second life, in top-down, isometric, view. I honestly feel bad for people who never had a chance to experience it in its heyday. It's still around, twenty years later, but it's a shell of what it once was. Great Lakes forever!
Yakuza 0 PS4- If you missed playing the previous entries from the PS2/PS3 era, this is the best place to start.
Alpha Centauri. This game is kind of a sequel to Civilization, even though Civilization has its own sequels.
Civilization. The game that started the franchise, and consumed an embarrassing number of hours of my life.
Dig Dug. Developed by Namco and published in America by Atari, Dig Dug had you tunneling around the screen while blowing up Pooka and Frygar with a pump, as well as dropping rocks on them.
Jumpman. The sticker on the box shown below indicates that it is the Atari version. I played this on the C=64 (my all-time favorite system).
Missile Command. The "Game Over" screen from Missile Command was the final shot in the movie Fast Times at Ridgemont High. It usually made an appearance in some way in most '80's movies that featured an arcade scene.
