I am so ancient that for me the most nostalgic games belong to C-64 and Amiga era. Ultima IV, Ultima V are probably the most important ones. But also Lord of the Rings text adventure, Dragon's Lair and Trapdoor. I remember watching my elder brother play Ultima IV with my dad and they wrote down everything that was going on, eventually building a real life "journal" for the whole game. It was massive.
