Remember 2019? Yeah, those were the days. I remember it like it was just a couple of weeks ago. Anyway, remember the 2019 Store Wars? And how they were going to ruin

In case you were lucky enough to miss the whole Store Wars business (and I’m hoping most of you did, because it was so silly in retrospect): in a nutshell, Epic Games started its own PC gaming storefront that operated in direct opposition to the entrenched Steam. It successfully drew in indie developers by offering a more attractive revenue split (and threw some pretty harsh shade at Steam and Google Play’s existing split while doing so) as well as a guaranteed sales minimum. It also snatched up exclusivity for a number of games that most likely would have come out on Steam otherwise — in some cases, even snatching them from under Valve’s nose.
