Roblox competitor Core brings free user-made games to the Epic Games Store

Roblox, for instance, makes most of its money off cosmetics purchased with the premium in-game currency Robux. Naturally, a percentage of every purchase goes to Roblox Corporation itself. But creators with popular games or creations can convert whatever Robux they receive into real money once they earn enough, and some people have turned Roblox into a sustainable – even lucrative – career. As you can imagine, this is partly why these kinds of user-made game hubs have become so popular. That, and their explosive popularity among kids and teens.

Though it's just now entering early access, Core has already amassed over 20,000 playable games in its yearlong alpha, with roughly 200 games added or updated daily according to developer Manticore Games. These range from shooters, RPGs, and side-scrollers to MOBAs, farming sims, survival games, and plenty more. The key selling point of Core is that "it's literally all there": in theory, its library of games is limited only by its users and the creative tools Core gives them. 

"By combining the power of Epic’s Unreal Engine with accessible tools that require no coding experience in a single platform, Core makes game creation, publishing and play available to everyone for free," Manticore says. It's no surprise, then, that the studio opted for Epic's storefront when choosing a public platform.
