Also, Predator, do you think Flintlock has been re-balancing the game so that it becomes a very close, until the end of the game, competition between the human and the AI players?
If so, well I have to disagree entirely. Flintlock isn't even in the ballpark of such "balancing" (I don't know if that was his intent), if that's what you thought his mod might do. Trading table usage combined with trade route pillaging is still available. I'm also guessing what enables such tactics comes as rather hard coded, and not something he can affect.
Below is one early save for you to look at that I played a few weeks ago and then stopped. It's a 60%, wet warm, pangea map. It's Sid level. The only AI technology the Maya lack is Invention. Some buildings got cash completed or assisted. Korea has some gpt available right now also. Germany and Korea both have extra luxuries, and Babylon and the Ottomans have some trade active. There's 68 gpt flowing from other civs to the Maya, and this is early. I'm not confident that all of the AIs have their markets up, and no one has a single bank. Horseman-knight upgrading seems rather feasible, and that's building knights at a rate of 30 shields for 70 shields, which at a rate of 3/7 is almost as good as the AIs cost factor of 4. And, horseman-cavalry upgrading is an even better rate, and just plain cash-rushing might work too.
The Flintlock Mod is amazing for using such trading table tactics. It's much less time consuming to find optimal exchanges than in regular civ III, and the autofill amounts haven't been anything other than optimal when I've checked.
