I think they'll have to sell out to a publisher eventually though.
80 million is triple-a territory, and without a marketing budget it's even better, but they are making a game that is far more than triple-A.
It's an FPS engine that's a Space Simulation, that's an FPS, that's in zero-G, that's an economy simulator, that's an MMO.
Right now they have, what, 350 people on it. That's a lot of money right there, without counting studio costs, the cutting edge motion capture, directing a single player for six months, actors, etc. etc.
Nice that it's rolling, but that money surely must be cutting it close now with the costs.
Bank loans or publisher deals are next.
