I don't understand the point of this post. What do you want us (players) or them (devs) to do with this information? It's long and detailed, nicely organized too! But what do we take away from this?
Adding to the points of why players don't play MP games and, why it's not necessarily an issue with want to play but, reasons of why this hasn't taken off and why players don't play this option and maybe suggestions on what would bring more players back into that option.
Looking at catering to small map sizes or quick games, when players do play long insane games but, not as many because those games take forever, doesn't mean that people don't play them just as much if not more total game time than people who play small, tiny games. Trying to bring attention that these stats don't always paint a full picture and they need to look at everything that's going on with all players and not just a general look.
