I might be wrong, but for now I’m not worried about it because I think this opening has been partially created by developers - particularly indies - not feeling like Valve’s earning their 30%. Of course that’s not necessarily totally fair - everybody thinks their game is worthy of prime front page placement - but nevertheless few are happy with Steam’s discoverability and promotion over the past few years. Then you add in all the Steam key selling stores that still take 30% for doing basically nothing because they can and it’s easy to see why Epic asking a much lower cut would be attractive even with their client lacking many relevant features.
