League of Legends is a 5v5 game with over a trillion game combinations, leading to diverse game play. ELO also diversifies the game, letting more skilled players be paired with their own skill level, and the people who aren't as good can play with their skill level as well. Also, League of Legends' characters are free, whereas Smite's are paid for with real money.
People earn thousands of dollars off this game, and can enjoy their occupation if they are good enough to make a living off of it. League is sort of like Overwatch, plus a tower defence aspect. Overwatch is a better game for people who like COD or HALO, but for more easy gamers, League is the Go-To.
