Much like WOTLK Classic, WOTLK Classic is all about collecting and raising virtual pet monsters WOTLK Classic Gold. The lead character in WOTLK Classic is a kid - an established WOTLK Classic trainer who is sucked into his electronic WOTLK Classic device and who finds himself in WOTLK Classic.
Not unlike the plot of Tron, the premise of WOTLK Classic is that behind the LED screen of your WOTLK Classic are actual electronic characters, not conductors and diodes. It's your job to save the world of the WOTLK Classic by finding all the lost WOTLK Classic, fighting them, and then convincing them to return to File City - the central metropolis of WOTLK Classic.
Since you're a WOTLK Classic trainer, you'll set out to find a WOTLK Classic to train. In the beginning of the game, you're assigned a WOTLK Classic, but as you progress you can select different digital monsters to train and command in battle. You'll not only have to look after your WOTLK Classic's needs, but you'll also be responsible for teaching him how to fight.
Every monster has stats, and good time spent in the game's training facilities will let you beef up your WOTLK Classic's powers. Each of the different training programs increases a different stat, letting you fully customize your monster's training. Additionally buy WOW WOTLK Classic Gold, each training will give you the option of a "bonus training," which lets you play a slot machine to determine if your monster will receive extra training points.
