I agree with him that 30% is a steep fee to pay for App Store revenues, but I just don't know if mobile & Mac sales were really worth all that.
I disagree that 30% is steep. The App Store significantly lowered eh cost of getting a game to market and in front of a large user base. Way back when a developer was lucky to get 30%, had to upfront all the costs of boxing, printing, marketting, returns etc. and hope they found a distribution channel and made enough to turn a profit. The cost to Apple to provide the service is irrelevant to its value to the ultimate purchaser, which is teh developer.
People argue lowering the commission will lower the price? How many small developers cut prices 15% when Apple reduced their cut instead of pocketing the windfall? I get why developers would do that, just don't argue it's pro-consumer.
Apple has a huge user base that pays more than Android and is a very lucrative market. That put a lot of money in EPIC's pocket and decided they wanted it all.
