But that's a bit of a false equivalence, isn't it?
A pro footballer plays football every day, as it is his profession, which he hopefully enjoys. (I don't imagine many people become pro footballers without loving the fuck out of that sport.)
Footballs are provided for pro footballers to perform. The football itself is not the singular object of a footballers passion, it's the sport as a whole.
For a shmup player, shmups are his hobby, he wouldn't put as many hours into it if he didn't love it. But he's not in any way obligated to play them as part of any profession.
A football is also not easily comparable to a product with lots of development time and money put into it like a videogame. Footballs can certainly be premium I bet, but it's not exactly the same. Also, to be able to play football oin their free time, any person will have to buy one.
I also don't agree that passion is at all defined by time investment. I agree more with Wikipedia's definition:
>Passion (from the Greek verb πασχω meaning to suffer) is a very strong feeling about a person or thing. Passion is an intense emotion, a compelling enthusiasm or desire for something.
Customers aren't obligated to do anything, it's the market's job to entice them to buy shit and if they don't, they've simply failed.
At the end of the day though if you get to enjoy something (a service, or a product like a videogame), they should get the money for providing it imo.
If the game is great, it would be worth it though, at least for me. Of course it's only natural to act in your own interest and wait for a sale or something if it's too expensive. Nothing wrong with that, as long as you buy it eventually. Every little bit counts.
I buy games because I like them and because I want to give back. It's a basic exchange, you're just buying a product, but in an industry where you have the choice to buy or not to buy, it gains a lot more meaning, I think.
