Not only does Epic refuse to make their game store any better, Tim Sweeney will continue to whine about how Steam's 30% cut is way too much. Surely if it's too much, Epic Games should be able to provide the same service for their cut? But no, they continue selling a moped while saying how all of the motorcycle manufacturers are ripping you off.
And lets not forget Tim Sweeney's dishonest representation. Sure, Steam can take a 30% cut, but they also offer a lot of avenues to avoid that. With Steam, a publisher can get a ton of activation codes and sell those activation codes on their site and not get hit with the 30% cut. No fee on in-game transactions, and as you build a user base for your games, Steam also lowers the 30%.
