Thanks for enjoying it!
Integrate with CIV gold? I've been lost in grad school... is there a new version of Civ IV? I updated this mod for the latest patch and imagine it works with the latest versions available by retail. Tell me more and I may be able to help you.
As for the future: no real huge changes, the few things I'm still unsatisfied with are:
1: Religion is too vanilla... and just plays as an advantage and diplomatic friction between nations... I want it to be more meaningful, but I'm not sure how I want to do this... no mod out there i've seen does what Iwould want.
2: Minor adjustments to the pacing as I encounter things that could be tweaked... as it is the balance is pretty delicately done, so I don't imagine many changes here.
3: Continue to monitor the government options to ensure that there are at least a few tempting reasons to be a monarchy or communist country late in the game... so far I think this is reasonably balanced.
4: Update it when the xpack comes out.
If you have input or things that could be added, let me know. Keep in mind the spirit of the mod isn't to make huge changes, add loads of meaningless units/techs/nations, but rather to add some flavor to each age, allow some time to be spent in each age, increase the challenge to the human without breaking the AI.
