Does how you play reflect who you really are? The Media Lab and Tilburg University are bringing science into the game to figure out the connections between our play style and our cognitive traits. To do that, we are gathering data from League of Legends, World of Warcraft, and Battlefield 4, and Battlefield: Hardline players to gain insights across all the major online game genres (MOBA, MMORPG, and FPS). In return, every participant will get an in-depth GAMR profile that shows their personality, brain type, and gamer type.
