You should go to CivFanatics if you actually care about Civ4 mods. There are quite a few active ones which haven't made it on here and the ones that are here don't get updated. There are a handful of very actively developed mods and several live projects that would benefit greatly from an infusion of new players and possibly new developers. The CivFanatics forum has a large list of hosted mods, plus tons of active developers with currently obscure projects competing for attention. Several mods add features and content to enhance the theme of the original game; others create entirely new worlds within that game, from space settings to Star Trek.

Warning: do NOT start playing Fall From Heaven 2 if you value having a social life or free time. It will consume your soul. Imagine Civilization in a fantasy world, with magic, orcs and elves and all that jazz. Now imagine tons of new major gameplay features - a magic system, in-game heroes, civ-specific gameplay mechanics that make the different civilizations play completely differently... All that only begins to describe the awesomeness of FFH. It has arguably more content than the vanilla game, and offers way more depth than an already deep and complex game. It's still in very active development, a forum with many active posters, weekly multiplayer games, even an active community of 'modmods' further modifying the game. All the best parts of civ gameplay plus tons of great new gameplay features add up to an even more addictive, engaging, replayable experience.

As a web developer I agree wholeheartedly. The problems people face with JS most frequently are DOM-related issues which are irrelevant to applications of JS that are not in the context of a web browser.

For non-web developers: DOM (Document Object Model) is the way that the browser translates both the content of the current page and certain browser-defined elements like the properties of the browser window itself, titlebar, etc. into an object to be referenced by Javascript. While there is a DOM standard supported by the World Wide Web Consortium (the main standards-and-protocols setting body for web technologies), no browser that I am aware of implements it perfectly; as with just about every standard, most browsers (Firefox, Safari, Opera, etc.) are very close to the standard with a handful of unique bugs or oddities each, most of which rarely matter, while Internet Explorer is miles from the spec. IE's implementation of Javascript itself is non-standard, too, which is the source of some of the notorious 'IE bugs' in web development; technically, IE does not implement Javascript but rather JScript, a proprietary Microsoft dialect that is nearly identical to standard Javascript, but not quite. A lot of the perceived clutter and inefficiency in Javascript code is due to the fact that most 'real' Javascript code has to include browser detection tricks (DOMs don't identify themselves; you have to snoop around for known differences to figure out what browser you're dealing with) and other messy workarounds to deal with the oddities of web scripting. Until you start writing mods designed to run on both Overgrowth and a multitude of clones which make lots of minor, poorly documented changes to the game and scripting engines, most of the headaches of web development won't apply :)
