My favorite is King Quest, Police Quest and Space Quest. Even though I finished them with the help of hint book (if I don''t, it''s impossible for me to finish them since I am a kid that time), I am really happy when I saw the ending.
Another old game that I remember is Digdug because my brother successfully play that game until level 99. My brother can finish it because the AI of the game is fixed, so the game can be play in a certain pattern.
