Everyone keeps saying DOS DOS DOS. Wasteland and Bards Tale were huge Apple // games. My Franklin Ace 1000 (with 4 awesome floppy drives!) played many hours of those and more.
Wizardry is still the best for sentimentality though...and Return of Werdna the most extreme example of annoying copy protection via manual . F'n dark maroon paper with small print and a huge code to copy every damn time you played...or was it each time you changed dungeon level...horrendous whatever it was.
