Doesn't matter if it's F2P or P2P I'm just wanting your opinions and preferably some good explanations as to why.
For me I say it's a tie between Horizons (Istaria) and FFXI. They both offered tradeskills that took time and effort into maxing them. Once you were maxed you were somewhat unique and in demand because of the effort it took. Your abilities also turned the tides of the world (especially Horizons) as you could make items that truly set you apart from the crowd or you could as in Horizons stake actually rebuild long destroyed cities and bridges opening up new areas for exploration.
