It seems very free, do you ever pay any money at all?
Is this game complicated to learn? I am interested.
I just registered at universe 22 and have begun to build a solar plant.
Can't figure out how to build a shipyard

My username is Kezzil and I am currently a n00b at this game, what I've experienced in other games is that it isn't smart to invest in n00bs because they will just spoil it anyway. I think I should just learn this game at start first.
I have a deuterium plant, and it says I have income. However, I haven't received any deuterium yet so I focus my solar energy on metal production.
I've built another solar plant now so I don't have any energy problem.
I've received my first deuterium!
Dammit, I should have invested more in metal production.
The sad thing now is that I will have to wait about two hours before I will be able to build my next metal mine. I have yet to see any current use of "espionage" and other buttons I haven't clicked yet.
I am making an Excel file right now to help me, this is obsessing.
I have a use of metal to upgrade my metal production, I don't see any more use of crystals right now (I have about 360 crys and I am waiting unil I've got 90 metal which I have almost got now).
Dammit, something useful costed real money - a geologist(10% extra mine production)
Do I still have possibility of joining in somewhere? (Kezzil)
*wonder what "cut your theeth" could mean*
Guess that mean I should try experience the game?
