Tasdik is right. Every server need something special and new. There's 2 ways to make own server popular. First way is to make something new and unique. I don't mean different rates or cap. I mean new uniques, mobs etc. like
this. Second way is, that you should've started server asap after files got released. But most of those servers are down or has low population, like Bloody and xcoding servers. Because their servers aren't unique. + they have problems with ddos or db leaks.
Edit. Look at
this. 76 pages full of silkroad private servers. Biggest reason why im talking about being unique.
