I can't think of any other platform with comparable expenses. Traditional game engines have the R&D component, but not moderation, developer services, or subsidizing games that don't succeed. It helps that seriously marketing a Roblox game costs < $1k USD always, usually < $200 USD. It's not easy to generate a loss, even when including production costs. That's the tradeoff.
