Supply Lines/movement range from cities would need extensive coding to work right. That is something that I think needs a full development cycle; it's been discussed in C2C before. As far as the tech ideas go, I'm not completely convinced that they make good gameplay without solid content ideas -- for the sake of gameplay, technologies need something to go with them or they feel forced, and I don't want that. I'd also really like to test my suggestions out before we go back for another round, but I also want to code and post the new content that is going to go with these techs. I've got the code modified up to the middle of the Medieval Era right now.
