Wow, I knew I'd gotten behind on the answers in this thread, but I didn't think I'd gotten that far behind. Sorry about that.
@Phoenix: No further futuristic techs, I'm afraid. We wanted to have some, but since we're still limited to 4 Eras in C3C, there's just no room for it anywhere.

As for the 'under-developed' cultures staying under-developed, I think it's something that would be great in a DYP Scenario, but in the standard 'Epic' game of DYP, all civilizations should get an equal chance. Try out Kal-el's world Map for DYP - it sort of tries to emulate this, at least for the American Indians and the African civilizations. I'm not sure if the current version of the map is compatible with the current version of DYP though. Checking that is on my todo-list
@SpaceCowboy_MA: We will definitely be using the 'enslave' option from C3C in Rise and Rule. As for the moral objections, they've always been around, but 'slavery' back in those days isn't slavery like we think of it today, and for that reason there wasn't as much to oppose really. Many societies held slaves in high regard, and in some societies slaves could even own property or other slaves. The early happiness hit just signifies that you've got a group of people living in your city but not of their own free will. Should the situation arise where tension builds up, they'll join any other fraction in an attempt to become freemen. That has never changed, no matter how well slaves were treated.

Can we have some teasers?
Yep, just join the betatest group in our forums
@Taltho: I know that someone managed to succesfully install and run the regular Civ3 version of DYP on a Mac some months ago. But I guess the main problem is that you can't use files with the 'EXE' extension, so you can't install the mod right?
@haegint: I'm doing the final tests of 2.02x tonight and tomorrow, and then it should be released. There'll be an updated spreadsheet released at the same time, I promise
@xraptorx: All difficulty levels have been slightly tweaked, but only very slightly. There shouldn't be any major gaps between Warlord and Regent - the biggest gap is between Regent and Monarchy, where the AI gets 'free' unit support in the latter, but that is exactly like in the regular PtW game.
As for strategies, there are a few threads in our own forums on how to play the 'early' game of DYP.
