THIS IS ALL OPINION OR SPECULATION!!!
ALSO, THESE ARE BASED ON MY EXPERIENCES AND ON WHAT I SEE WITH OTHER INVOLVED PEOPLE
I hear a lot of complaints about the story being too closed or limited to a few people/older guilds. One day I was talking to some people and some theorys about why people feel this way came to me...
To start off, I've been fortunate to have had a fair amount of involvement in the story and the events as they stand, which I think makes me in a position to make these comments...
First of all, BE INTERESTED. This has a few parts... try to take part in many events, either player or FC. Funcom seems to pay attention to people who are involved, and additionally it gives them an idea of how you'll react in a particular situation which makes it easier for them to interact with you. A subsection of this (and this can be really hard) is find a position, and try to stay with it. If you go along with EVERYTHING that any GM says, you're less interesting, and in my experience less likely to be involved. Choose a position and stick with it.
Second, be INTERESTING. Engage with them... try to show an emotional reaction and make it as 'real' as possible. Also, come up with something original. I know this is obvious, but I'm trying to be complete.
Third be POLITE. I don't mean don't yell at them if its appropriate, but don't constantly harass them or ask about things they can't control (like game function). Try to remember that whatever is going on (probably) isn't totally centered on you.
Fourth be AWARE. My obsessive tendencies help me with this personally... Keep an eye open for when the Story elements are present, and go check it out. It never hurts to investigate.
A few side notes, It DEFINITELY helps to be a guild leader. This is both because you know about things sooner, and because being in such a position makes it make more sense for them to interact with you. Also, looking back at this alot of it is VERY obvious maybe... but I'm tired of some of the complaints. Its sometimes unfair, I'll admit but these things can only help your involvement.
Also a certain number of events are totally open, and for those none of these are necessary, albeit still helpful. Remember they listen to all the public channels all the time. (one time a GM totally freaked me out by replying to a comment about her by me on the Clan Leader channel).
I hope that this is interesting, and at least a bit helpful... Also, comments welcome! let me know how stupid I am!!!
