It's a very basic rip of what jagex has, because it takes ages to make the exact replica and even with multple coders working on a single project it can get very frustrating so it would take excess cost to get it done because if they just put osbot on hold when they don't even have as much time as they used to when they started osbot up, they would be doing way less than they are for osbot as is. You should look further into rsps resource communities and try building one, even if the person who makes a "flawless" copy of the current version, it would still have flaws because why would they release a game that is bringing in 9$/month per person who pays for membership release a version of their game?
