Absolutely, WO. The point is simply: CivIV is the best place right now for some kinds of modding (ie, the trailblazing, "How the hell do we do such and such?" kind of thing you're up to right now), and CivIII remains the best place right now for the other kinds of modding (eg, the "Let's make such and such a scenario"). One day, no doubt, CivIV will be the place to do the latter kind as well, thanks to the efforts of you and those like you, and I look forward to that day. But it's a long way off yet - perhaps just as well, not only because of the amount of projects still in the pipeline for CivII, but also because I suspect that working out how to do all that stuff, and laying the groundwork for future libraries, and turning out the first experimental units etc, is a fun enterprise in its own right!
