So why not just allow people to turn the "always peace" option on? ...you shouldn't be able to just go through an entire game with no chance of ever fighting at all. It's part of the game, it's part of the challenge. That's why even if you have +15 relations with a civ that doesn't mean he won't declare on you.
Good question, because the Always War option seems to be allowed, which has the same detrimental effects on the AI as Always Peace would.
This is similar to one of the most amusing things about the gotm "predator" game, most times these disabilities simply weren't. While giving the AI more free units might deter a less skilled player the real effect is that the AI performs better, has more gold available for trade, techs better which can be easily gotten thru trade, etc. The net result is that the human performs better when compared to non-predator players.
Anyway, ignoring the main point for a moment, your statement about the +15 rep is misdirected. The reason the AI still declares at that is because the AI sucks, and they have no honor, or any other moral we would typically see in most humans.
Since there are no "real" treaties between nations the rep system should act as one to some degree, and +15 is well into alliance. Although, I've had no problem maintaining the peace with quite a bit less than that so its really a null point, thus Always Peace would just be a crutch, taking place of game skill. This applies to Always War as well, although it doesn't seem to affect the AI vs AI relations so is just a silly variant not an exploit.
In summation, there can be no trust, just as in Civ3. This is obviously a very bleak worldview, but I'm not really sure who is responsible.
But all this comes down to one point which you and others are not addressing. (Other than why you feel the need to impress your play style on others.) What factor are barbarians adding to the game that we want or need to have present?
As previously stated, "leveling the playing field" and such nonsense is invalid because you can play with or without them based on your own choice. If you have to disable them to compete with a given game or score, then do so. I fail to see any problem there. What I am asking is what makes forcing barbarians on such an attractive option? I'm quite bored by them, they are very predictable, psychotic and their only advantage is they don't require resources or production (and so "cheat").
