It takes forever to make server ,i just started to learn about l2j and etc though i will done in less than 1 month ,but lol? i guess il finish in 1 year xD (really) ,and from my point of view ,is worth the waste of time ,because making a server like you wish and knowing that most of players would like ,its more fun than playing your favorite server ;)
The only special custom servers from my opinion are L2Dreams,L2 Blackbird,L2 Dubai (weird servers with neither exagerate custom and neither simple = balance)
PS: The same way you wasting your life to have fun staying playing games ,is the same way with creating a server ,you have same fun feeling and etc ,that's why even if you fail or you wasted a year creating a special server but you don't have enough money to host it isn't a regret ,is a preview of your own capacity and make's you know that you're better and help you TO go on xD ,after all most of us are boring of life and we try to create something special
My conclusion is that people who like copy/paste and fast things and they don't put soul and effort ,are the kind of people who like drugs,sex,alcoohol and they have a selfish personality (haha lol rly ,call me crazy) ,conclusion 2: you don't wanna talk to these kind of people or having a deal with xD
