which is fun and nothing is cooler than growing, buying clothes, weapons or armor, mounts and literally endless things that will make you feel that you advance and progress and what happens next? Nothing,
I think the goal of the MMO is to compete against other players. Growing a character, buying clothes, weapons or armor, mounts, all of that leads to PvP or Guild War. It is the same thing with online shooting video games, among us. Winning and Losing is a part of that game that makes it more fun for people who play it.
it's all in the tastes, personal challenges and desire to play <3
