You already gone so far beyond the errr.....beyond expansion, adding...what 2 new eras? now that's a feat, you guys will end up growing beyond the civ 4 game and having to build an entirely new game like the FFH guys were planning!
Seriously though, it's all good stuff, and as I've stated before I just wish I had a platform powerful enough to do it justice, as it is I usually have to play on a tiny map just to get anywhere, which only give me glimpses of how great the mod is while I struggle (or not) against only 2 AIs and a handful of barbs....my poor little laptop cannot cope with anything larger and tends to crash often.....trouble is I never know if it's due to me pushing the laptop too far or if I've hit some bug in the coding (always worries when the screen does an odd "shift", usually signals the game is about to crash....but not always)
Strangely one of the features I've found to be the most useful is the Sentry wake with land/sea buttons, such a small feature but makes so much sense.
