> Steam provides payment processing,
Other services do the same for arbitrary online shops, at much lower fees. In fact, Valve likely doesn't even run it's own payment processing, but merely integrates other services.
> cloud saves, ratings, game tags, social integration, wishlisting and sale notification, search indexing, game discovery, a bunch of incredibly useful APIs including networking and input, Linux compatibility
The development cost of these features is likely no larger than of one single AAA game. Yet they charging 30% on hundreds or thousands of AAA games and other games.
> This is not only false, due to the above value-adds, but intentionally false because I never gave a definition - you made one up and attributed it to me to lie about my positions.
You clearly stated that Steam is fine because it is useful. But anything sold by a monopoly can be useful while still being massively overpriced. Which proves that mere usefulness of something doesn't mean the price of it is justified. Which refutes your original usefulness argument.
> And yes, there is competition
Yes, but the fact that there is theoretically competition doesn't mean it is working. Large platforms like Steam benefit from network effects which come from their size alone. People will simply stay at Steam because that's already were their other games are, and because they don't see the massive 30% fee, that Valve is keeping, as some cost they have to pay. Any other platform faces a "chicken and egg" style uphill battle against these effects, even if they charge a substantially lower fee.
> Your comments are false due to your total ignorance of reality, and your malicious lying
Rather than hurling insults at me consider the simple question: If Steam was so fairly priced, wasn't charging excessive fees, how can it be that they have an extremely high profit margin? Realistically, that can only be because Valve's revenue from Steam vastly exceeds the costs of running and maintaining it.
