best advise i can give you is : you will certainly read tons of negative things about this game on the forum, don't let those things scare you and try to focuss on the positive ones, because yes, this games has some huge downside but also has lots of great stuff to discover and is definitely worth trying.
Anyway no matter if you choose f2p or p2p server, league or empire, may the force be with you and i hope you'll enjoy this game as much as i do
