Don't put the project out there too openly yet, too many people who will play the early stages and never come back again for whatever reasons, people who will see empty servers and just think it's already dead, etc. In fact, this happened within the community even, with GPP. I didn't like GPP at first (I actually still think it's garbage overall), but when I came back later on the public games were tolerable and brought some entertainment. 1.1 players I tried to convince to come back still had terrible images of GPP and just didn't even bother. Avoid that.
Imo, the game needs a "polished Alpha" before it's going to be viable to give good information from games being played. And even at that point it will be better just to stick with players from the Trem community itself. That might be tough to do, but it will hold its players better when it's not giving half or more of the people bullshit problems.
I think that, when the game gets to Beta, there would hopefully (but it's very unlikely) be enough players to keep on going without advertisement. At that point, maybe go as far as possible with the beta, up until it becomes difficult to really improve it much without drastic measures being the ideal situation. Then advertise it everywhere, setting the stage to pull in a bulk playerbase, to which you display clearly active development.
