Not even just a feeling - they really can build these experiences themselves. I just watched our 5-year old kitbash together a city full of cars in about 4 hours, which is now online for anyone to visit.
I find the platform very appealing even as an adult, as you can script in Lua, and then watch as hundreds of visitors interact with what you just wrote. This week I hacked the Bad Apple music video to run on Roblox, and then had a great time seeing people react to it.
