As Exact-Psience said this is a great list. I would add the Fighting Fantasy books to this of which there a a few now. The only problem with Lone Wolf and the Sorcery! books are that they are such good conversions , with totally new presentation they make the 'old' Fighting Fantasy books look a bit primitive now
(i still love them though)!
