@metzli In my opinion all that you mentioned are high effort. I play splinterland too and I enjoy gaming in general.
However the question you ask is how you monetize it. It’s a valid question. To monetize anything you need a consumer. If your gaming content can earn $300 just like your freelance work, more power to you. But it is up to you to scale your time and effort accordingly. Right now there is no content out there in steemit that can pay $300 for an hour for your effort. So I am sorry to tell you that at this point in time this platform is unable to sustain your requirements.
I believe in the blockchain. At this moment, I feel wealthy, but am not feeling wealthy enough to invest in my future (traditionally speaking, using fiat) my steem blockchain efforts are for me to reap the rewards of in 10 - 20 years. Let's hope I am right in investing my time here.
