I bought a games pack once for my Commodore with four cassettes (!) and Bard's Tale was one of the games in the pack. The game contains puzzles, riddles, a lot of random combat and magic spells, and I became quite addicted to it buying the other games in the series rapidly making hours of fun and frustration (due to bad English skills).
