Just like with civ 3 s expansions, Play the world, then Conquests. Firaxis has a habit of withdrawing items that should have been in the orginal and plugging them into multiple expansions. Although Warlords is the only one too be announced, i will bet anyone that a 3rd will be on the way. Firaxis can you please concentrate on patching and updating the original, rather than making us have to purchase multiple expansions to get what we should already have in the vanilla version. I dont think its too much to ask for the developer to be as devoted to the first version of Civ4 as they are to every subsequent expansion. FIX CIV4 ORGINAL BEFORE YOU RELEASE ANY BLOODY EXPANSIONS THANKYOU!
