What are the oldest computer games you sill pay?

It wasn’t that long ago that I gave Fool’s Errand another spin.

From coin-ops, lots.

Rygar, Solar Warrior, Robotron, Vanguard, Burgertime, Mr. Do’s Castle, Super Qix, Juno First, S.W.A.T., Black Tiger, etc.

But from older PC games, not many because I can’t figure out how to slow down the Dosbox. I loved Wing Commander 1 and 2.
