If I had to pick only one game, it would definitely be Dungeon Master for the Amiga (1987).
First of all, nostalgia plays a huge role. I used to spend entire days with it when I was younger, completely absorbed in its atmosphere. Those memories alone make it special.
But beyond nostalgia, the game itself has an incredible depth. It’s full of surprises, challenges, and clever mechanics that always keep you on your toes. There’s so much to discover and so many ways to avoid succumbing to the dangers within its dungeon.
