Normally an arcade cabinet has a bunch of buttons and big red-tipped joysticks. When it comes to a League of Legends arcade cabinet, you get a mouse and keyboard to play. Let’s face it, playing a modern RPG without a mouse and keyboard would suck.
Part of the appeal of MOBAs like League of Legends is that they have tons of playable characters. You know who else has tons of characters? Disney. DeviantArt member Elasar Reem turned just a subset of Disney characters into LOL champions.
