How do I stop the hard AI from ganging up on me (or survive when it does)?
So, I've gotten bored with stomping the AI on Normal. I've tried playing some games against a Hard AI instead, and while I can beat it in 1-on-1 or even 1-on-1-on-1, I'd like to play with more AI players on a larger map. But the hard AI always allies with itself against me!
My games go like this:
~0-30 minutes: I colonize a few worlds and start building a fleet and infrastructure.
30-60 minutes: A few forces from comptuer players assault my border worlds. My fleet manages to hold them off, but because I'm being attacked on two or three fronts, I don't have resources to spare to counterattack, and it's hard for me to continue growing my economy.
60 minutes: Five computer fleets, each containing at least as many ships as my entire empire, attack all my planets simultaneously. I either surrender or spend 15 minutes being ground into the dirt.
I know I'm probably not building up as quickly as I could if I had a little more expertise at this game, but how can I
possibly defeat a fleet that's five times my own? The only way I've found to survive is to lock the teams when I start the game, but that feels like cheating and also means the whole diplomacy aspect of the game (such as it is) is shut down. I can't run the missions the computer hands me ("fly across the map and destroy structures owned by player X") without leaving myself open to attack, but that seems to be the only way to prevent the Allied Fleet of Doom (I've successfully used this approach on small maps with 2-3 computers).
Does anyone have any advice? I'd like to be able to play single-player games without having to choose between a cakewalk and a meat grinder...
