Thanks Joseph, I'll take a look at them.
I recently fired up Civ IV again. I had been frustrated with the endless AND betas never quite being finished and the direction AND had been heading, so I recently cobbled together a build of 1.75C with bunch of selected civs from the Mega Civ pack. I also merged in a few balance changes from 1.76 like Walker Mechs and the Attack strength changes for archers and light swordsmen based on technology, but left out the hated Commando on horseman. I'm playing a huge game through and it SEEMS pretty stable so far.
I read K-mod is mostly an enhanced engine that doesn't have RoM expanded gameplay yet? Maybe I don't know where to look for the latest version? Vincentz' mod looks pretty on target and has a couple neat things, maybe I will give it a shot at some point.
I am really hoping my 1.75C variant doesn't have major problems, because it is probably one of the best versions of Civ IV ever made. I've read some folks complaining about later era stagnation, so we'll see.
