I have learnt this the hard way. Often, people like to make experiments. They hire people like me as freelancer and then they hire juniors fulltime. They want results, good results in possibly a short time. Then our collaboration ends, experiment failed.
Why is that? Because people hardly accepts the reality of games. Making games is a serious thing. You will never make a good game with people part time. You can use part time freelancers, like me, to create specific content for something that already works. But if you want to make a new game you need to really invest heavily time and energies in doing it. 100%. There is no shortcut.
I always speak this clear before with my clients “this is hard, it will hardly succeed. I cannot dedicate more than X hours per week. You need more.”. Nothing. They want always to try. And sometimes they get upset because of the results.
Don’t be upset, I tried to warn you.
