i don’t think unreal is under the same pressure for three reasons:
they already have a reasonable revenue sharing model. they make a lot more per licensee than unity does because they take a cut of your sales rather than charging a per-engineer license for the dev kit.
epic’s headcount is not nearly as horrendously bloated, even before the recent layoffs.
the company is still privately held with Tim Sweeney the majority owner.
points 1 and 2 mean epic is actually profitable, and has been for decades at this point. meanwhile, the publicly traded unity has struggled to break even for most of its existence
