Am I the only one who thinks that it is just a bit unrealistic that you can just draft an entire planet's population to put on a transport? I think the game needs some sort of of "recruitment" system that makes soldiers seperate from civilians. I have touched on this in another post but will go into more detail here:
Every turn, the computer takes your recruitment number (RePs), multiplies it by each planet's approval rating, maybe divides it by some other set number to balance it out ( I won't even attempt to come up w/ that number right now) and applies it to that planet's population. The number produced from this equation(sp?) becomes the number of soldiers enlisted into that planet's army.
The number of soldeirs recruited per planet per turn should range from the low 10s for very low-recruitment civs to the 10,000s or even high 100,000s for very high-recruitment civs. Note: Numbers may need to change in order to achieve balance/realism. Note 2: These numbers are based on the assumption that while 1 "unit" of population actually represents 1 Million people, 1 soldier "unit" actually represents one soldier.
The base ReP number is treated like all other numbers e.g. affected by political parties, racial abilities, etc.
You can build improvements like recruiting offices, conscription centers for evil civs, etc. that raise your RePs @ the planetary or civ-wide level, maybe even a galactic resource or anomaly.
There is a slider on the Domestic Policy window that sets your recruitment spending. Note: 0% Recruitment spending does NOT equal 0 RePs. It's like the colony propeganda slider from GC1. It is one way, albiet probably the main way, to add RePs to the base stock each player is assigned @ the start, along with improvements, maybe anomalies & resources, and techs.
After each turn, recruited soldiers are stored on the plantes they came from, just like regular popolation, maybe with a cap that cam be raised by "military base" improvements, techs, or other stuff.
Maybe have a lag from when you change your RePs to when those changes actually appear, since soldiers need to be trained for a few weeks.
Transports can carry soldiers from one of your planets to another, when they do so, they drop off their passengers, enter orbit, and when launched can pick up more soldiers.
For invasions, the soldiers from the transport fight to the death against the soldiers on the planet. If the invasion succeeds, the planet's population stays the same, and the surviving soldiers become that planet's soldiers.
