I love TEC the most. It seems that TEC is more well-balanced overall than the other races.
Economically, TEC can research metal and Crystal extraction ( You will only need 1 Civic Station ) faster than the other races . One of the upgrades that I like the most is " Modular Architecture ", it decreases the cost of extractors, frigates factory, and some other building. This is very good early when expanding is important. TEC also has the Immense Cargo Upgrade that give you metal and crystal income faster from your refineries. I think TEC is the best when you are talking about economy.
Militarily, TEC has the highest armor and Hull points for ships. TEC's ship can not be destroyed easily especially when you use Hoshiko Robot Cruisers that can repair hull ! The support units isn't so bad for me. Some people try to use Arcova Scout Frigate and Timed Explosives upgrade for a rush. This is a good strategy because most people just ignore the scouts and 3 bombs will destroy most structures. For Capital Ships, I like Kol Battleship the most. It can take a lot of punishment and its ultimate ability, Finest Hour, can give it an edge in battle. For starbases, I prefer TEC's starbase.
Do you know what I don't like about TEC ? It is the ships' design. They are not elegant and symmetrical. I always like Advent's ships in design.
So, that is my opinion. What do you think of my English ? It is good enough ?
