Storage for most of it. Spacing is crucial and consideration of the room as a whole. If you need to display everything like this, get all matching symmetrical glass fronted cabinets and light those suckers up. Even a huge ass clusterfuck display will look so much better with nice furniture.
>>7152049As far as arrangement strategies go, this is a pretty good one. Simply not collecting the smaller stuff will simplify your life much.. I don't get people who are compelled to buy it all. Can they all be enjoyable good toys? Maybe... but do you *need* it?
Also I don't think this sort of autism appeals to many people but the uniformity and symmetry thats possible in army building will avoid some of the traits of a clusterfuck.
As far as toppling goes, proper stands like Bandai's Tamashii Stage Act series.
