Okay, here's a suggestion for a few Role Playing Games, all the Bard's Tale games, Wizardry 1-3 and 5, Might and Magic I and II (if you can find copies online that aren't .nib, which is impossible to transfer back to real disks). Also possibly any of the Ultima series, I have them but haven't played them, though there are people who swear by them.
Elite (the father of the space trading/fighting genre), F-15 Strike Eagle, Silent Service (a great submarine sim), Destroyer, The Hunt for Red October, any of the Carmen SanDiego games, Summer Games I and II, Winter Games, Space Rogue, Sundog, just as starters.
If you've looked through the Asimov archive you know those are just the tip of the iceberg.
As far as Applesoft programming go to www.1000bit.net and get to the Apple Computer section under Documentation. You'll find a couple different books from Apple about Applesoft programming. Another thing you could do is check eBay auctions for Applesoft books.
Hope this helps,
Magnus
