Huh, I'm not sure the full intent/scope of the list but Bungie shipped a LOT more games with custom engines than just Destiny. Marathon, Myth, Oni, and Halo, to name a few.
It is certainly non-exhaustive, i think it just mentions some examples. REDengine for example was used not only for Witcher 3 but also Witcher 2 and Cyberpunk 2077.
