Human Vs Comp question

[Master Belisarius]

Although a moded AI can build warp openers/closers, rarely use it with a real advantage for the AI.
Mostly (only?) will use it to open warp points to uncharted systems.
If the human player close all the warp points to save their planets from the AI attacks, the AI will have not a clue that need to open a new warp point to continue the attacks against their enemy...

If you want to see the AI's use Warp Opening tech, then start a game with the No Warp Points box checked. I did this with standard AI and found the game was too easy. The AI's don't put in any extra effort to get Warp tech. I had about 8 systems connected before I saw any AI's opening Warp Points! (I had see scores active and so could see how many systems AI's had.)
