How these alternatives were chosen
Tools Unreal Engine names as alternatives that this directory also publishes, followed by others in Software. The order is not a ranking, and "—" means we have not checked that field — not that the answer is no.
Unreal Engine also lists Godot, Unreal Editor for Fortnite (UEFN), CryEngine, Amazon Lumberyard as alternatives. Those are not in this directory yet, so there is nothing to compare — and nothing to link to.
