In Concept art & 2D assets, Leonardo.Ai ranks #5 and Dreamlands ranks #10. No independent quality tests found. Ranked on game-dev fit: commercial use allowed; no engine integration stated; API and official MCP server. Leonardo's own models are on Artificial Analysis's text-to-image leaderboard, but near the bottom (best: Lucid Origin Ultra, #86 of 102), so it doesn't move it up.
Whole environments, building kits and matching props in one style
General concept art and icon ideas
What it does
Agentic 3D world building: concept art from a sentence, then matching 3D props, modular building kits, PBR materials and whole buildings from a floor plan, exported to your engine.
General image and video generation platform with trainable custom models; usable for concept art, item icons and texture ideas.
Verdict
For building whole stylistically consistent worlds and kits for Unreal, Unity or Roblox; commercial use is allowed but non-exclusive, and Dreamlands can reuse your generated assets.
For general concept art and icon ideas; free-tier output can be used commercially but is public and Leonardo holds rights to it, while paid plans give you ownership.
