File data: This is often very dense data like 3D models, textures, animations and terrain. Our user interface is built up from XML and Lua files. Many of the art files do not use the same file formats that commercial art tools spit out. Our build pipeline takes these raw art files and translates them into something optimized for our game to read and process.
Note: My goal here was to create a comprehensive list of everything you'd need in order to learn to play any class (from Level 1 to Naxxramas)—meaning I am only including class-specific resources here (so no profession guides, general leveling guides, etc). Teeb's Resource list is much broader in scope, and I highly recommend you take advantage of it (as it contains a plethora of non-class specific resources as well). If you're not aware, Teeb is also responsible for the Race & Class Comparison Tool, Dungeon Tier Sets Gallery, and a huge variety of other insanely useful resources.

If you’re into MMORPG games, you’ve probably heard that World of Warcraft is preparing to release a classic version of the game this summer. However, not many people have played in the real Classic and current in-game classes might seem completely unrecognizable to some. In the early days of World of Warcraft, the class choice was very important – leveling was super slow, which meant that you could get stuck with your character for months.
“By the way, one of these codebases [Vanilla WoW] is extremely buggy, and we had already solved a lot of those [bugs]. But we can’t solve them [this time around] because... ‘reasons’ if we’re thinking about the Classic timeline. And so we really struggled with it for a very long time, and one of the things that we talked about when we were discussing different ways to do it was to do what’s called a ‘fork.’ So we did a fork of our existing modern server stack and then reimplemented the systems that we needed to support Classic WoW. And made sure that the tuning was right and imported the old data, we had the old code and a way to compare. Having the backend tools, and the backend server, and the modern hardware was a requirement to realize this project.” Essentially, what the team did, was teach modern WoW to speak old Classic data.

In this form, there is much less wasted space and spells are no longer limited to three effects. But before we can load any database data, we need to transform the old data layout into the new one. This is not limited to spells, as almost every game system (including items, creatures, player characters, spawning, AI, and more) has had its database layout altered over the years.
