I think the lack of social interaction with the finished product is the culprit.
On these day of Minecraft and Roblox, Viewing the creation is not enough and making a labo kit is also not as entertaining as watching someone make a minecraft castle. You have to be in it and play the whole thing. That's not a good platform to bet on. Not practical and not convenient for everyone.
