I have upvoted and resteemed this post to help you out. However, speaking honestly as a dev myself, this post isn't overly compelling. The details about the project seem too vague, it feels more like an idea that hasn't been properly thought out yet.
As a bare minimum, you need a project website and ideally a business plan. How will you make money? What is the MVP going to look like? When do you want to launch? I suggest before building anything too detailed, you write some specifications on the different facets of your game. The underlying mechanics, how things will be balanced and so on.
Also, offering tokens with no value might not be a compelling enough sell for most developers who see this post. Understandably, you you might not have the liquid Steem to give out, but there are other ways. I suggest offering equity in the idea, offer developers a percentage of the overall expected profits.
I will be keeping an eye on your progress and when things develop a little more, I might jump in and help you out on the front-end. Until then, good luck and I really hope you succeed. More dApps on Steem is a good thing.
