Well what is fun really depend by players, for some people is fun playing in a relaxed way for other people is fun playing in a grindy way.
In my case, when i play a game like pso, i really hate being a low level ungeared player, i just want to learn more things about the game and get stronger. The point for me isn't to be " the very best like no one ever was" i don' care about being stronger than other people but just enough strong to do everything in the game correctly and fast. Cause for me is fun doing things correctly and, if i do things in the correct way, i feel like i did good. I really dislike being carried by other people, i'd just like to be as strong as them so they don't have to carry me and i can feel like i did my part. Also i really enjoy learning strategies for the missions, learn spawns and using correct weapons. But i have not enough experience in this game to do it :/ Anyone should just play in the way he finds fun, and never pull on other people to play as he wants to play. If a thing is not fun for you it might be fun for another people, PS: Anyways that player was really bad mannered lol
