And both of these posts point towards the same conclusion: that in a social situation like an MMO, smaller might actually be better. Currently, most games are fascinated with being as big as possible-- a "world" of content to explore, or "millions of players," all in the same space. MMOs have "expansions," and ever larger instances and battlegrounds-- the bigger the world can get, the better the selling point sounds.
But should it? Blizzard, the world's most famous MMO maker, has determined in the past year that a group of 40 doesn't work nearly as well as a group of 25, and that doesn't work as well as a group of 10. And as much as players say they want to play with their friends, just how many friends are we talking about?
