Friend list, community and reviews are all thing that matter to developers too, because they'll only increase the interest people has on that game, hence buying the game, because of its "social" features, cloud for saving progress on a game is also another important thing. "Worst platform is an opinion mostly pushed forward by flaming reddit posts with extensive lists of feature gaps" I sincerely hope you're joking, you understand this makes no sense right? That list is legit and has a clear point, objective point, not subjective, those are facts, and lacking those feature make EGS worse than steam, and the worst in general, since the other smaller launchers have more feature than that. Refund? Wanna talk about it? Mods? Doesn't matter that flaming t**d of Metro doesn't have mods, many games on PC do, and that's a PC platform we're talking about. NONE and i repeat NONE of those features listed are subjectively useful, they're all OBJECTIVE USEFUL, hence subjective useless. What do you mean with "steady trend of people getting their content elsewhere"? Steam does offer more to both devs and users, which automatically means offering more to devs again. My use of devs in this discussion isn't appropriate, i know, but it's to make it understand better what i'm trying to say.
Steam doesn't offer their engine, that's for use if you want, it's not a feature they offer with their platform, what's your point?
They offer much more Grants to indies than epic, what are you talking about. Free content? Who cares about that, besides steam offers that too. Again with the interaction of unreal engine and unity engine, what you're saying makes no sense at all, engine are a different, separate thing, that's not a feature EGS offers, per sé, nor Valve.
