It's funny that you mention that but pretty much "the MOBAs" genre came from the fact WC3 engine shipped with editor. And big part of SC staying power was because of community made maps and stuff. CS (which gave birth to Valorant in turn) and TF2 (which Overwatch traces lineage to) also came from mods. So it's not really the license just sheer fact community can take it and start modifying if it doesn't work, or evolve if it gets stale.
