I suppose your explanation does make sense. It does seem to have been awhile since the last turn.
My conduct in a game depends on what I decided to play as at the beginning.
As Klingons I DO not use ship computers, bio weapons, or planet destroyers.
As Terran Empire (ST mirror) I will spy, I would backstab if I feel I can get away with it (always with the hope the player doesn't take it personally), and "cheat" within the game. eg. I would break a treaty after I had moved in to position.
I can see the benefit of forcing AIs to surrender, but as the Dominion I fought the Andorian AI only for the Federation on the other side of the galaxy to suddenly annex them
Of course after that I demanded all the other AIs to surrender.
I have been avoiding new SE4 games so I can play SE5 but it doesn't look like that will be starting any time soon.
