In the organizer's words:

Deep in the shadows of decades past, where flicker and pixel noise pulsate like ancient signs, a fabled book has been rediscovered: the RETROnomiCON. This mystical work is full of lost gaming worlds, iconic pop culture artifacts and legends that were once only passed on in whispers among fans.

But RETROnomiCON is more than just a book - it has come to life. An entire convention rises from its pages: a living journey through time, where you don't just browse through stories, but experience them first-hand. When you open the book, you also open the doors to a world that unites the past, nostalgia and pop culture in a single convention.
RETROnomiCON is being organized by the cultural association BS Oldschool for the third time in 2026. Previous editions have taken place under a different name, but each one has allowed the work to grow until it now reveals its true form.

Its pages seem to breathe. Chapters only open up when you enter the rooms of the convention. One thing is certain: RETROnomiCON draws everyone into a world where past, present and living fan culture merge.
