Either way, they do the same job, and I'm glad OSRS is getting plenty of new content that isn't copied from RS and existed in 2007

My favourite bit about old school (well, technically the purely old school community, the ones who play both are more sympathetic, I'm sure), is the like/dislike ratio some people like Sparc Mac's videos get when he shows RS3 content. It's crazy.
I don't watch them very often personally, my friends just showed me the other day and I thought it was great. As you say, not like they took anything from RS3.
