Vasari - for the voices! "eYYEEE can wait no LONNNNNGERRR!"

tec for massive amounts of cobalts

All will join the Unity, in time.

I just love capital ship skill synergy. And having a useful colony capital is great.

TEC for the Novalith and the Kol Class.

Random, for the "I WIN" button.

Anyway, I prefer Vasari for the ships designs.

TEC for the Capital ships "Kol" and the "Kodiak" for the front lines.

Wow, and here I thought I'd be in the minority. Advent is my fav, has been since 1.0, just because.

Vasari and Advent.

The Advent are great. I like Vasari a lot, too but...I just finished a 6.5 hour game with Advent. I love the illuminators and their siege frigates, plus their technology are just plain useful. All hail the "experimental weapon" mixed with the cultural upgrades. The cap ships are great too...I am convinced that one of each of their caps at max level could take out the other factions' under the same conditions. I also love the massive damage the, as I have dubbed it, "Ion Cannon" (three guesses what this is) does with all possible bonuses attached (including the Malice and Guidance abilities). Altogether great fun to play as, although a bit slow to start.

All three factions have their advantages. The TEC have awesome battlecruisers and when they level up they can become beasts. With the upgraded GAUS ability they can do up to 800 damage in one shot. The Vasari definitely have the firepower. They also can gather resources the fastest. Also, fully upgraded phase stabilizer tunnels can call in reinforcements of 3-5 Heavy Cruisers, 3-5 long range frigates, and carriers FOR FREE. I had about ten planets with these and I didn't have to build any new ships for the rest of the game. The capital ships have great deseigns and so do their frigates. Heavy cruisers do 28 damage and have good health. Also, fully upgraded skirmishers and missle ships do about 13 and 17 damage respectively. Though tha capital ship abilities aren't that great. Now my favorite are by far the advent. Their capital ship experience ability is outstanding. You can quadruple the firepoqer and abilities (which are by far the best in combat, especially with a mix) of each capital ship with having to guard it closely in every fight to get the experience. Illuminator vessels do about 20 damage and only use about 5/6 supply. Also the Destra Crusaders are strong with the added ability to do 1.5 damage per second to any enemy in range. (This can Add up)

TEC, 'cause no matter how much I hate people, I'll never abandon my species.
And because we've got the best of:
Music
Voices
Appearances
Armor
Hull Strength
Brute Strength

And you can't deny how awesome it looks when a Novalith shell hits a planet.

Hi I have only really played TEC so they are my favourite, plan to get good with vasari next. I aint playing advent until after the next patch since I dont want dissapointment. I dont even think I have built a novalith yet , the research is so big! hopefully I will be able to try some other races in a few weeks but TEC seems really intuative even though their late game ships in certain circumstances feel squishy. I like them because the way they are balanced Im having to think about many aspects and well I think that should improve my game throughout time. Watch this space in the next few weeks though as I will be trying vasari soon, they sound good in their own way.(but heck they all sound good in their own ways!)

Mostly this depends on how you play. A standard, economy or mixed def-off based player will probably like TEC, mostly because they are easy to use...like the U.S. forces in CNC Generals.
The Vasari are more for the CNC Generals Chinese players...their firepower is nice, and you can quickly get both resources and more ships, if necessary.
As for the Advent...GLA...this is because it is harder to get resources with them, but their strength is tremendous once the economy stabilizes. Another strength here is intelligence and cultural influence, since a specific upgrade allows cultural influence, not your fleet, to determine your sight range. This is nice, especially in long battles.
