True that. The game does have something for everyone. I play as Vasari and my favorite cap ship is the Jarrasul Evacuator AKA The Great Space Egg, that is because of its ability to colonize, the nanodissasembler it eats anything in its path, and because of the kick ass drain planet ability. Also just some advice or build order these are the very first steps that you should do when the game starts.
1) Build a Capitol Ship factory to get advantage of the free Capitol Ship.
2) Build all the Extractors on your planet preferably the crystal onefirst.
3) Go to the black market buy 100 crystal (Click once) and then go to your planet and upgrade infrastructure, its the green button and in that menu the first button with a person.
4) Buy as many scout frigates as you have phase lanes.
5) Build a Colonizing Capitol Ship
6) Build attack frigates while your cap ship is building, stop building frigates when cap ship is done.
7) For the Capitol Ship give it the colonize ability and a squadron of fighters (always fighters)
8) Take your small fleet and attack the nearest asteroid and destroy the forces there first and then colonize.
9) After you colonize the asteroid research the infrastructure just like you did to your home planet.
10) Build extractors on the asteroid
11) That is all that I will say the rest I will let you find out for yourself.
Hope this helps and welcome to the 4x RTS Genre. Have fun with the game.
Ps: Never build colonizing frigates waste of money.
