Just a few:
Zork & Co. from Infocom. Already described well enough above.
Elite: Likewise.
Paradroid: I’m amazed how many people never heard of or played this game. Any list of Top 10 games I’ve seen for the C= 64 has this listed. It’s not all that hard to figure out, you’re some little droid controlling unit on a space ship and you have to destroy all the other droids. Since your weapons suck, you hop from droid to droid, blowing them up with your stolen weaponry until the droid you’re on burns out and you’re forced to hop to a new droid.
Archon: The IBM version of this game sucked after playing the C= version. I mean, you could hit the phoenix while it was flamed! What’s up with that? Sort of a Fantasy Chess game where the pieces actually fight when they take a square (in actual controleld combat, bot pre-canned moves like Battle Chess).
Pirates!: Never before has such an amazingly simple and repetitive game been so addictive to me. Take ship, go to port, get men, take more ships, get more men, take a few cities, divide the loot. Repeat about 2500 more times until you’re a Duke of the French, Dutch, English and Spanish.
Mail Order Monsters: I loved this game, and it was funny to see the Goblins from Archon imported into those club weilding dudes who lived in the mountains (Wampas or whatever they were called). Buy a monster through the mail from the catalog, equip it and send it out fighting to earn more cash for better eqipment and genetic upgrades.
Adventure Construction Set: I saw this first in an advertisement in an old copy of Compute! and read that ad some 30,000 times. But I could never find the game because it was out of print by the time I saw the ad. then one day, I found it in the discount bin at Sears. Bought it and loved it. I used to convert favorite novels into adventures and make my friends play them. But I have to say, the adventures it would generate itself sucked big time. Each one was “go to point A to open point B to get into point C to…” until at point H or I or so, you got the breifcase and won the game. Or something dumb like that.
Pool of Radiance/Curse of the Azure Bonds/Secret of the Silver Blades: Those and the Krynn series sucked up more of my time per week than school did. Was I the only one who would sit outside the library in PoR and “Rest” for 1 year, 6 months, 2 weeks and 3 days just because memorizing and casting cure spells was such a chore? Thank God for the “Fix” button in later games.
BASIC games I loved were the Lemonade Stand one, some game where you had to build a house in one month and figure the materials cost and time involved (never won that one) and my all time BASIC fav, “Hassle Castle” where you had to explore and fight your way up to the ground floor of said Castle.
