The Unreal franchise was Epic's flagship product for many years. UT is a natural platform for esports (cf. CS:GO). Sure, UT might not be casual enough for everyone, and Epic was right to focus on Fortnite when it blew up, but why Epic hasn't marketed UT as an "elite" gaming product and put it at the top of its esports food chain is beyond me. I would expect it to provide a halo effect for the rest of their products. (And besides, there is so much untapped IP in the Unreal universe)
