I'be gotten so sick of cheaters that I've started playing games with just one human and the rest AI. But it's not that fun becuase the AI players are really bad, and the humans know how to game them.
What's worse is the ridiculous level of bias displayed against hosts. I'm in a very typical game right now. After two turns i was down from 30 to 12 troops, all coming from AI players. The other human was on 32.
Another example is when I try to hold a region or continent, the AI will do whatever it takes to make sure I don't succeed. But the human player can leave 3 in a border and and not be bothered at all.
