Clifford 1994 . My favorite Martin Short movie . <| sep |> Surely you could find something , even remotely related to dota . Finding a paper about purely dota is way too optimistic , and I think you ' ll have to settle with relating articles in the areas to the games of your choice . Furthermore , since your topic is very broad are esports legitimate sports you ' re likely going to have to address several areas from ' skill levels ' to more detailed areas of psychology and statistics considering the game does have significantly more ' random ' aspects that are out of the players control , compared to everyday sports . Hell , I had a cursory look and found a few articles that could help you out , I honestly think focusing on individual games is probably what ' s causing your trouble . Anyway , that ' s my 2 cents .
