Most people here are saying the same thing which all games is my favorite.I do play CS GO,LOL and DOTA 2 but I really like to play dota2 and lol which is the most enjoyable and favorite mmropg game and ive been playing it for 3 years on both games therefore I know whats the mechanics and which teams are the best.
i will like to say that i mostly play gambling on sports games and i think the reason is that in sports gambling you can use your experience your skill and your knowledge that can favour you while playing gambling.
