I\'d have to say that in reality the only way the oldbies are \"better\" is because they already understand what works, and what\'s necessary, for RP, guild-making, etc. etc. etc. So yes, it\'s basically amassed knowledge, technically if a \"newbie\" could come into the game with all this, then they wouldn\'t be any worse than the \"oldbies\". I have yet to see this happen, though. There are smart newbies, but none who understand PS as thoroughly as the oldbies.
At the same time, I realize that there is such a thing as a stupid oldbie. Those are people who are totally clueless even though they\'ve been around forever and/or think they\'re awesome just because they\'ve been around(off and on) for years. Often they don\'t actually know squat. Arrogance is one of the products of this.
Personally, I think people who understand PS deserve the respect, not people who\'ve been around for a long time, often though, those are the same people.
