It is an office, with rows and rows of computers. RS3 ones don't seem any different to OSRS ones - there'd be 2-3 monitors along with a person. We talk for their OSRS gold team in the canteen and kitchens (or the pub) - it is not like a Montagues/Capulets air if that's what players are imagining. Besides, I have like 6 decades of my code in RS3 in the 2007-13 era, and some of it I'm very proud of (e.g. Love Story quest). I don't know a lot about their future projects. And no, although we do have a lot of resources from 2011, it is not a complete build that we could boot up on release and demand - even if it were, infrastructure things such as the chat system, names, saved bonds and games have shifted considerably since that age, and they would require a lot of adaptation to create that build work. Just like Mod Philip did to acquire OSRS at the first place, only the one that is 2011 could be larger.
I was until a week in the team. We are perfectly friendly with each other, although I'd say we operate otherwise. I would state that RS3 and OSRS teams and each other certainly don't talk much as they do inside themselves. But they're both an extremely relaxing and friendly bunch and I really believe they could talk longer. RS3's got a skill coming that I'm very much looking ahead. As for 2011scape, I really don't know how many different time periods this company could assert, but we're at risk of collapsing the universe if we do too many...:P Presumably, the more RS games, the more fragmented our community?
Though we do sit little individually from the RuneScape team, it is not nearly as divided as people might expect! I've got some great friends on the RuneScape development group, and the teams are constantly communicating, sharing understanding between games, etc. - we've got plenty of shared learnings, for 2 games which are still so similar at their cores!
A ton of those players are those that played Runescape in their teens back in the mid-late 2000s, and therefore are reaching age of becoming families / occupations / difficult years in college etc.. That means finally less time for gambling, and our game is notorious for it can take to buy RuneScape Mobile gold to level up skills, and progress. For me this means a part of our struggle will be to diversify our offering to some degree, we cannot remove from the core game, that expertise is exactly what it really is, and shouldn't change - but by playing new ways like Leagues that offer rapid advancement, we could provide something which does not require such attention!
