The Video Game Museum is a smaller museum in Berlin https://www.computerspielemuseum.de/, but it has a lot of fun early history personal gaming equipment, with playable units. And including a lot of euro gaming and (at the time of my visit) running demoscene items I knew little to nothing about.

especially the demos are (over-all) astonishing! I still remember the cracks made by phrozen crew and razor 1911 in the '90ties. They incorporated demos into their cracks of a few dozen Kb - that was awesome! What an audiovisual experience! That was my first time I heard about the demoscene :)
