Species - Trogarchs

These guys are also extremely warlike, they're just not as bright. Trogarch military equipment is ordinary, save only at close range. By way of compensation, at least their stuff is cheap.

Strengths and Weaknesses

Prefer Methane atmosphere worlds with temperate or cold climates and high gravity. Can put up with all atmospheres except Oxygen and Hydrogen. Low gravity is intolerable.

  The Polyphim, the Klaa'Keen and The Hive are their competitors for living space. (Actually, The Hive is a competitior for everyone except the Sprnadoi. They can colonise just about anything.)
Research Facility costs are high, discounted by an Era 8 Colony Improvement.
Hull Types have plenty of weapons and shield capacity, are cheap and available fairly early.
Shields are plentiful but not very effective until the late eras (Era 7 for CAs and Era 9 for larger ships). They are never much good for DDs.
Propulsion systems sluggish and no Military Improvements are in the pipeline.
Astro-Navigation is average
ECM is ordinary but cheap. There are useful Military Improvements in Eras 5 and 7.
Offensive Projectiles are okay, particularly at Close Range. DNs and SDs can mount a reasonably balanced broadside, smaller ships are vulnerable at Long Range. Planet Attack capability is pretty good.
Defensive Projectiles are poor, except at Close Range. At least they're cheap.
Beam Weapons are cheap and very good at Close Range. Their ineffectiveness at at longer ranges means you should not assign more than 20% of your broadside to beam weapons.
Military Improvements are very limited; ECM, Beam Penetration and Planet Attack are the only areas addressed.
Colony Improvements are available to reduce the cost of R&D facilities (Era 5) and improve Trade Rating (Era 8), among others. Remember, the Trogs are thick which accounts for their limited Improvements.
SP costs for Era jumps are fairly low. This will assist tech flexibility.
Warlike nature may restrict diplomatic opportunities in multiplayer games.
Low trade capability does improve in the late game (Era 8).
Base Rate of Fire is 35. Ordinary.

Default Production Queue
The first couple of times you play the Trogarchs, I recommend you configure the default production queue as follows, especially in the early game.
I1 / I2 / R1 / I3 / D1 / R2 / D2 / S1 / M / I4 / C / D3 / S2 / R3 / D4 / S3 / R4 / S4
