Roblox vs UEFN vs Core vs Rec Room: Which UGC Platform Pays Developers Best?

The State of UGC Platform Economics

User-generated content platforms have evolved from hobbyist sandboxes into legitimate business opportunities — but not equally. In 2024, Roblox paid out $922.8 million to creators, crossing $1 billion in the trailing twelve months ending March 2025. Fortnite's creator pool distributed $352 million. Core and Rec Room, by comparison, operate at fractions of those figures.

The raw numbers tell one story. The revenue share percentages tell another. Developers choosing between these platforms face a genuine dilemma: chase the biggest audience at unfavorable rates, or take a fairer split on a platform where the audience may never show up.

Breaking Down the Revenue Share Math

Core offers the most generous stated rate at 50% revenue share — the highest headline number in the industry. Rec Room's Partnered Creator Program targets 40%, with 250,000 tokens converting to $150 USD (a 50% rate improvement introduced January 2024). Fortnite UEFN runs a pool-based engagement system where Epic allocates 40% of Fortnite's net revenue monthly across qualifying islands, with a December 2025 promotional period offering an effective 74% share on direct item sales — the most creator-favorable policy any major platform has announced.

Roblox sits at the bottom on percentages: 24–30% effective take-home after Apple/Google platform fees and Roblox's own cut. A September 2025 rate increase to $0.0038 per Robux and the launch of Creator Rewards — which 73% of developers reported improved earnings — softened the criticism somewhat. Premium paid-access games fare better, reaching 50–70% depending on price tier, but standard free-to-play titles remain the most squeezed of any platform here.

One structural problem with UEFN deserves attention: Epic's own first-party maps compete in the same engagement pool as independent creators. Battle Royale's playtime draws from the same revenue bucket that UEFN developers are trying to earn from — a conflict of interest the developer community has repeatedly flagged.

Audience Size: Where the Real Gap Lives

Revenue share percentages become almost academic when audience sizes diverge this dramatically. Roblox reached 150 million daily active users in 2025, generating over 10 billion monthly hours of playtime — a figure analyst estimates place above Steam, PlayStation, and Fortnite combined. Roughly 58% of that audience is under 16, and 80% plays on mobile.

Fortnite's last disclosed figure was approximately 126 million monthly active users in 2023, with a meaningfully older demographic (49.6% ages 18–34). UEFN has grown to 70,000 active creators publishing over 200,000 islands — but discoverability remains an unsolved problem. Players default to Battle Royale, and surfacing UEFN maps to that audience requires either algorithmic luck or significant organic reach elsewhere.

Core and Rec Room operate in an entirely different tier. Core is PC-only via Steam and has never published verified player counts. Rec Room's estimated daily active users sit around 150,000, with a Steam concurrent player peak under 2,000. For developers evaluating these platforms purely on potential reach, the gap is not a gap — it is a chasm.

Tools and Development Experience

Roblox Studio remains the gold standard for accessibility. Its all-in-one environment — combining 3D modeling, physics, and scripting in LuaU — pairs with the largest tutorial ecosystem of any platform here. First-time developers can go from zero to a published game faster on Roblox than anywhere else. The trade-off is visual fidelity: Roblox's engine produces instantly recognizable low-fi aesthetics that increasingly feel limiting as player expectations rise.

UEFN is built on Unreal Engine, with access to Nanite geometry and Lumen global illumination. The visual ceiling is industry-grade. Epic's proprietary Verse language is more capable than Lua but steeper to learn, and documentation was notoriously sparse at launch — a gap that has narrowed significantly through 2024 and 2025. Verse Persistence, which shipped in March 2024, finally allowed creators to save player progress, a feature Roblox had offered for years. For developers with Unreal experience, UEFN is a natural home; for everyone else, there is a real investment cost.

Core shares UEFN's Unreal Engine 4 foundation but wraps it in Lua scripting familiar to Roblox developers — a thoughtful bridge that has not translated into meaningful market share. Rec Room's MakerPen takes the opposite extreme: no-code circuit-based logic that works in VR and on flat screens. It is the most accessible creative tool in this group for non-programmers, though complex mechanics quickly hit its ceiling.

What Developers Are Actually Earning

The earnings data clarifies the practical stakes. On Roblox, 885 developers earned over $100,000 in 2023 and 105 crossed $1 million. The top 10 developers averaged $33.9 million per year. Brookhaven RP alone has generated approximately $56.1 million in total earnings. Even the broader top 1,000 averaged $820,000 annually — up 570% since 2019.

UEFN produced 58 creators earning over $1 million each from engagement pool payouts in 2024, a meaningful milestone for a platform that only launched its creator economy in 2023. Core's platform average runs to roughly $1,000 per creator across ~50,000 creators — a figure so skewed by a small number of top earners that it offers little guidance for new developers. Rec Room's most successful creators reported lifetime earnings up to $30,000 during the matching bonus era that ended in late 2023.

The pattern is consistent: Roblox's low percentage rate applied to a massive audience produces the largest absolute numbers by orders of magnitude. The frustration in developer forums is real, but so is the difficulty of leaving.

The Verdict: Which Platform Is Right for You?

There is no universal answer, and the honest framing is that these platforms serve different developers at different stages. Roblox dominates on earnings potential — its audience scale makes even an unfavorable revenue split produce career-level income for top creators. If your game targets under-16 players, social experiences, or casual mobile audiences, Roblox's reach advantage is nearly impossible to replicate elsewhere.

UEFN is the platform to watch. Industry analysts at Naavik and Konvoy describe it as a sleeping giant: Unreal-quality tools, an engagement payout system with improving economics, and a December 2025 direct sales policy that is the most creator-favorable major announcement in this space. The remaining challenges — an unstable payout formula that has been revised multiple times, a discoverability problem, and Epic competing in its own creator pool — are real, but they are solvable. Developers with Unreal skills building games with strong player acquisition loops should be on UEFN now, treating current volatility as early-mover opportunity.

Core and Rec Room are viable only for specific niches. Core suits small teams who want Unreal-quality output with Lua scripting and are comfortable with a limited audience. Rec Room is genuinely compelling for VR-first social experiences and brand commission work, but insufficient as a primary income platform for most creators. Both platforms have treated their developers fairly — they simply have not built the audiences to make that fairness financially meaningful at scale.
