Now I have no idea who has this game at the moment that already has a complete set of CivIV. But I'm curious, are there any modders out there that did stellar work for CivIV that will move onto CiV once the SDK is released? I can think of a couple off the top of my head. Rhyes, as well as the FfH guys (I thought I heard something about either one of them moving the mod to CiV) did some amazing 'alternate' gameplay. As for modding the original game, will the BUG mod dudes as well as the Better AI dudes jump ship from CivIV to CiV?
