how many shoppers just eat the cheese and walk by withouth buying a block?
Does it matter if the net sales increase enough to make it worth it?
Many, many moon ago I was playing a game where the devs were still trying to charge by the hour.
I begged and pleaded with those guys to try going flat rate. They were so terrified that 5 guys in a dorm room might all share the account and take turns playing. I was like, "What do you care? More than likely those guys wouldn't have gotten individual accounts anyway and worse case scenario you have players in the arena so the people who are paying have someone to shoot at." Never could convince them. Arena had fewer and fewer paying customers with less and less action. No critical mass. Colony collapse. Game shut down.
But boy they made sure there wasn't two guys in a dorm room robbing them of a subscription. They showed them.
At the time AH went flat rate that was revolutionary. They saw the market had changed and they innovated and crushed the competition that still stubbornly trying to stick with an outdated hourly monetization model. It was a risk, but failing to evolve with evolving market expectations is also a risk.
The market has not stopped evolving since.
