I mean a lot of artists do gigs for money, or work as temps or interns in large companies - neither of those jobs are likely to get you credited. At the same time they also produce their own stuff. Same for other lines of work, software devs code for other people's software. It's not nice but it's how many people earn money, I was just pointing it out not endorsing it.
Yeah, but there is a big difference between a large company, and a small freelance game studio. Work structure is also different. Besides, just think about it. Besides, the comparison of lines of work is kinda non sense. Because not all of them manage their work the same way. For some artist, large companies are a great place to grow, mainly for begginers, if they want to work for a large company, and then, after that, being able to be on their own on projects. But you know that many people that worked that way, in the end, they preffer to be on their own, not getting stuck on those companys.
But, for small studios like must the ones here, depends on the users, and their support, and bc of that, they most handle things on a different way(And yeah, not all of them have the same experience on the freelance field, so some of them have hard times handleing things). Above all, the freelance workers that depend on being know for the people to be able to keep working.
