What Is the "Biggest" Free Game? Depends on Your Metric

"Biggest" is undefined—could mean:

• Player Base: Fortnite, League of Legends, Roblox (100M+ MAU).
• Map/Content Size: Genshin Impact, Warframe, Destiny 2 (100+ GB, years of updates).
• Development Budget: Fortnite, Apex Legends, Valorant (AAA live-service scale).
• Scope/Depth: Path of Exile, EVE Online (free tier), Dota 2 (infinite skill ceiling).

No single winner. Define your metric (concurrent players, world size, content hours, competitive depth) and I'll name the leader.
