First of all wish you best lack with anything u do , i dont want to be the bad person arround but after 5+ years in L2 and L2J i will say this , community is full of failed server which mostly split the ppl from the few decent servers arround , i like the way players do by DDoS the freaking new and old server , cuz a decent server wont have problem to protect . Since i get the feeling that you and your boss have not idea of development programming , desinging and the rest the whole server will be on the mercy of your developers , so if u dont like something he will be able instantly to screw ur project up , this happened to lots of server , so instead of you and ur friend being the boss , the developers will earn the boss place and u will be just a decorative and follow because of this . You might find a trustfull person ofc and u could never have this problem but i dont think so , anyway most of ppl prefer interlude atm , PvP servers are the best and easiest choice not much of a setup and no stable players ur community will have random ppl daily few of them will stay for even a week but they will refresh if server is a bit intersting , the hard choise is a stable and good low rate which i will personally was going to spend time , i miss the old l2 times of exp and a good server with events , GM's care and ofc fun and PvP .
Best of lack !!! Friendly always :)
