If you win the game in the original AI War, aside from getting a big flashy "YOU WIN" sign the actual game does not change.
What I means is that should you chose to continue to play the game then it seems you destroying the AI does not affect the remaining AI forces. They continue to be reinforced, exo-galactic strikes keep getting sent against you, etc etc.
My humble proposal is that when the player wins in AI War 2 that this has a actual effect on the remaining AI forces in the galaxy.
The effects should be, in my opinion.
- AI Forces stop receiving reinforcements
- All AI held systems no longer communicate with one another, meaning all units in a system act as defenders for that system alone. They don't ever leave.
- No attacks are ever mounted on Human forces, no reprisals, no threat, no exo-galactic strikes and no wave attacks.
- AI Progress no longer has any effect on the game or remaining AI forces
The idea being that should a player want to keep playing and to re-conquer the entire galaxy from the remaining AI forces, then that should be feasible. It would be interesting none the less.
Assuming such a thing is not difficult. I think a similar circumstance occurs in the exodian blade ending.
