I think a lot of this Epic hate is misplaced. There are many reasons why games decide to go the Epic Games route.
Frankly, game devs gotta eat. For one, being sought after as an Epic Games exclusive is more money in their pockets to pay their devs and perhaps create better content.
Also, people forget Epic actually gives devs MORE money per purchase than Steam. Epic takes 12% whereas Steam takes 30%.
All in all, Epic Games is a much better choice for MANY devs than to go to steam. Yes, Epic's store needs improvement, but it's also still a new store. Changes will happen over time. There are many applications you can use (like Playnite) to combine store libraries into one location.
Just want to clarify I'm not saying it's necessarily a good CONSUMER practice to be on one store and not other stores, but I'm just laying out the many beneficial reasons WHY devs choose Epic over others. To be honest, I'd prefer devs choose what they want, and I'll follow. If the game is good, I'm satisfied there!
Regarding Sins 2, am really excited. I'm a fairly new sins player but it's been the one RTS I've been able to get a grasp on. I love the economy system, and love how it's an RTS with 4x elements sprinkled in. I can't wait to see how this new game differs and how it'll improve on an already solid game!
