In Civ 3 there was a really handy editor that was similar to the Civ 4 Worldbuilder, but it also let you set unit abilities and building effects. The Worldbuilder in Civ 4 seems to only do map stuff and setting up for scenarios, which isn't what I'm looking for. I just want to change the water units to have more movement, multiply all gunpowder-era units' power by 10 and all modern era units' power by 100 (still too many problems with tanks dying to spearmen). What is the maximum attack power a unit can have in Civ 4? I would also like to add some effects to some world wonders so that more of them put a building of a specific type in every city, similar to how the Eiffel Tower puts a Broadcast Tower in every city. Is there any kind of visual-based editor like in Civ 3 for changing these things, or do I have to learn programming? I'm a noob to all this. I did post here once a few years ago about the XML files, but I gave up because I couldn't understand them and was too frustrated with what I see as game imbalances to keep playing.
