first, chek out the strategy forum, there are a ffew threads going about this atm
--------
The following takes place in the first 5 sec of the game
--------
Build a capship factory
sell 100 metal
buy planetary upgrade
build a crystal extraktor( getting it first is about 30 sec extra crystal incomr good at the beginning)
build 2 x metal extraxtors
queue up the capship of your choice(colonizer for advent / vasari - marza or kol for TEC) the first one is free
-------
from here it is much more playstyle and map dependant, but the first thing you sshould colonize is an astroid( cheaper / faster to get them to give a profit)
hope it helps
