Eh, 2010s ain't got nothin' on the 1980s in that regard. Every movie had a sex scene, and at least half of them had boobs, for no reason other than fan-service.

Plus, half the reason for lack of interest in Flash is that in franchise terms, it's a "dead man walking" --the whole DCEU is getting the (re)boot after this, so there's no incentive to watch this installment when you know there'll be no payoff for anything it sets up.

Inflation?

As long as they're still making money selling ES:O expansions, why devote the resources for an all-new game?
