Hmm, I wasn't aware there was. Like what for example?
Some people take the game more competitively than others, or give more to the game than others.
You can amount to A. making a map. B. Making a skin. C. being a CM member. D. creating Scenarios. E. partaking in Alpha.
You can also amount in different ways. I am competitive and feel special that I'm #1 in the world at something right now.
You can amount to your squad in the FSO for getting lots of kills or bombing lots of things.
You can amount by winning KOTH or a few other special events.
You can amount by being a cool person who people like flying with, and meeting new friends.
You can amount by helping other players learn the game better.
There are a bunch of things people in this game can do to amount to something. Whether that is personal achievements, or creating things for the game. Even partaking in events can allow you to amount to people's work in setting them up.
While it is just a video game, people do enjoy it and people do take it seriously. Some take it seriously or competitively and some dont.
I dont think it should be discouraged to attempt anything I've written above, and in fact if you do amount to something in this game, you make the game more enjoyable and playable for everyone else.
