Godot Engine Shows Exponential Growth on Steam in 2026

Games developed with the open-source Godot engine are racking up Steam reviews at a pace that analysts describe as showing “strong signs of exponential growth.” High-profile early access games like Slay the Spire 2 are boosting visibility for this free engine.

Godot’s rise aligns closely with the post-Unity pricing crisis of late 2023. Unity’s controversial runtime fee announcement drove thousands of developers to seek alternatives. Godot, supported by the nonprofit Software Freedom Conservancy, welcomed many of those developers. The commercial success is now becoming evident in Steam’s data, over two years later.

Mega Crit’s choice to use Godot for Slay the Spire 2 instead of a commercial engine adds weight to the discussion. The original Slay the Spire sold over 2.5 million copies and remains one of the most influential deck-builders ever. Its sequel, set to launch in early access on March 6, 2026, at $24.99, quickly attracted over 100,000 concurrent players. This shows that Godot can support high-demand commercial releases without issues.

Currently, Slay the Spire 2 boasts a 92% positive rating based on 60,667 Steam reviews. This score places it in “Overwhelmingly Positive” territory, despite being in early access. The volume of reviews gathered in less than two months highlights strong player engagement, drawing attention to the technology behind it.

The growing momentum for Godot is crucial for the industry’s cost structure. Unity and Unreal both impose licensing fees or revenue cuts after certain thresholds. Godot, however, doesn’t take any cut. For indie studios and mid-sized developers, this difference can determine whether a project is financially viable. The expanding list of commercially successful Godot titles lowers the perceived risk of opting for it over more established engines.

By The Numbers

Slay the Spire 2 Steam Review Score	92% positive
Total Steam Reviews	60,667
Current Concurrent Players	105,609
Steam Price (Early Access)	$24.99
Early Access Launch Date	March 6, 2026

Community reactions to Slay the Spire 2 have been mixed, influenced by factors unrelated to the engine. One Steam reviewer stated, “It’s a fun game but why hire someone like Anita Sarkeesian that only makes the game industry worse???” This sentiment appeared in several negative reviews and led to a brief review-bombing following Mega Crit’s first balance patch in late March. The studio publicly defended that patch, and the game’s overall score has remained well above the 70% threshold despite the backlash.

What To Watch

• Godot’s Steam market share: Analysts are pointing out signs of exponential growth now, but the next six months will reveal whether that trend continues or levels off as the post-Unity migration games are released.
• Slay the Spire 2’s 1.0 trajectory: The full launch of the game is set for 2026. How it performs after early access will determine if Godot can support a major commercial title through a busy release window without technical problems.
• Engine adoption by mid-tier studios: So far, Godot’s commercial successes have mostly come from the indie sector. Keep an eye out for any studios above the indie level that commit to using Godot with a supported marketing budget.
