Start marketing ASAP in the process. Gather and involve fans as much as possible to get them invested.
Finding players is more difficult than finding developers.
SO:
Deliver value to whoever you can. Delivering value gets you an audience.
The long-term value is in the long-term thinking.
And (to my thinking) delivering value along the way as best you can so that those people you helped might in-turn help you directly or indirectly in the future.
In that sense, think of marketing as like Karma.
I hope this helped and delivered value to you, my fellow #gamedev #indiedev #solodev folks.
