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.
Who is Joana?  Joana, (AKA Mancow, or FuriousPaul) speedran 1-60 vanilla WoW from 2005 - 2007.  I have been server first to level 60 seven times in a row, along with winning Blizzard's "First to level 50" contest they held back in 2006.  I also have the fastest time through original vanilla 1-60 WoW in 4 days 20 hours. I have produced a very useful 1-60 horde speed leveling guide along with a 1-60 speedrun video.
The original WoW was painful. Mobs took forever to die; one additional enemy in a fight was a pain, two probably meant death. There was a ton of running. Most buffs lasted two minutes, many took reagents, abilities were trained and often out of reach if you lacked the necessary gold. Warlocks had to farm shards, hunters had to carry ammo -- even my warrior did, since in vanilla WoW she can carry a bow and fire arrows herself.
Discipline: Premonition - Heals nearby targets within 20 yards for [ 75% of Spell Power ], and applies Atonement to yourself. Deals [ PS * BC1 ] Shadow damage to yourself for each Atonement you have active, and increases their duration by [ 5 + 0.1% of Spell Power ] sec. Holy: Rapid Mending - Prayer of Mending is now instant cast, and its jump range is increased by 10 yards. Shadow: Void Origins - Void Eruption is now instant cast. Rogue

In OSRS, before bonds (their equivalent of tokens) were released, there was a strong gold industry, but most people who bought gold did so by buying bonds on the main game, then finding a dedicated 'swapper' who'd exchange their RS3 gold for an appropriate amount of OSRS gold (taking a cut for themselves, of course). I wonder if a similar system will pop up in classic wow

 ":"  -  Any time a step ends in a ":" instead of a "." means that the next step is part of the current step you are on.  This generally means the next step should be done while working on the current step.  This means every "start working on" or "continue working on" will end in a ":".  But this is used with other occasions as well, so keep this in mind.
I think that the token is a nice solution for the problem. Back in the days, blizzard tryed to ban gold sellers, but it was a lost cause. Instead, the token seems to have resolved the problem, letting workers that want to raid with consumables and stuffs to have the golds to do it. Personally, I don't find the gold buying really fair, but I understand that for many people is a necessity and I prefer to leave the economy and the farming spots to the player instead to the gold sellers.
