Right now in my game, I have troop transports that can carry 5 troops each. I have 12 of these in a fleet, and 3 of these fleets. I can effectively put 180 troops on the ground in a matter of minutes at any planet I wish to invade. It is a for-drawn conclusion.
The Problem: It is often far to easy to eliminate an AI empire via invading their home planet. Once this planet goes, they are doomed, period.
The Symptoms:
- Not enough defending forces
- Too easy to load an overwhelming force for an invasion
- Too easy to build transport capable of carrying entire armies
The solution:
1. The AI needs to be coded in such a way that it maintains a set number of troops on a planet based on population. These troops will not be laoded onto a transport, it is the planetary garrison. Any troops above the minimum number can be loaded. This way the AI does not load all its defensive force onto transports and leave its home colony undermanned (works for the player AI as well).
- Up to 100m population: Minimum of 1 troop
- 101m to 250m: 2 troop Min
- 251m to 500m: 3 troop min
- 501m to 1b: 5 troop min
- 1b to 5b: 10 troop min
- More than 5b: 20 troop min
2. The troop transport component needs to be increased in size to 50 just like the fighter module. This will limit the number of troops that can be transported on a ship. If the troop transports were bigger, you could only put a 1 on the starting ships (when the AI is at its weakest) and would need to research construction to build bigger transports.
3. Bigger defensive bonus.
I think if these 3 things were inplemented it would go a long way to alleviating the problem with AI home planets being over-run so easily early in the game.
