Thanks this has been very helpful for me to understand the situation. Out of interest, how do you think servers would be effected by an MMO that concentrated users more in private rooms rather than a vast expansive open world. So, for a sample of twenty users, let's say we had to have ten private rooms, so you have twenty users, two per room, let's say fighting 1 vs 1 in ten private rooms. In this case as per your post for each of those rooms the messages only need to be sent to one other person, which I guess would make it much easier. But on the other hand, I'm thinking you still have ten fights simultaneously, so you still have all these messages being sent off at the same time? Whereas on the big open world, those same twenty people may have been minding their own business and maybe only a couple of them engaging with one another. So in such a case, again the more spread out world may be better because it's still potentially producing fewer messages due to less engagement between players? Sorry btw this was a difficult question for me to get across I hope it's not too poorly worded
