If you say the same, I repeat the same. It's not about owning ideas, is about owning the results of my work, if I (or anyone else) make a videogame, I did it, not you, so it's up to me to allow you to use it or not. If I did something like saying "I had that idea first", it would be something stupid, but if I made something real of that idea, and you're basing your work on the real thing I made, you shouldn't step over me. If laws about it are fair or not, or even if the price at which things sell is fair or not, would be a different topic. I'm personally on the side of trying to find the way to skip the most middle persons and dealing only with the essential people so my work can be sold at the cheapest price possible within a reasonable profit for me. My work has a value and deserves credit, don't tell me I shouldn't have the right for it.
