As for being selfish - nope, not saying that at all. There are some great players from all over the world in other time zones. What I was trying to point out is the reality that the bulk of players are based in North American time zone - and maybe that is something to be considered when trying to increase numbers. How do we tap into the overseas market of players? Why is it North American based so much / popular here and why do we not have that level of success elsewhere in the world?
Many reasons. Outside of the US kids don't have credit cards (I have no idea if squeekers are even a target group). The world-wars are not a great thing to remember, or re-play. Military is not something to worship. Planes are noisy and dirty, and only for the rich (unless when needed to go to vacation).
When there is advertisements, they are targeted at that market (I think? Have never seen one here).
While there is no translated versions, I doubt that would matter much these days. But people around the world at least use different kind of keyboards. While the mapping-per-(physical-)key is the same, something different is printed on the keys in different locations. It surely reduces the chances of keeping a player if the chat bar cannot be opened, because the key left of the right shift key is labeled with something else than /, and the instructions explain to press /.
What I noticed is, that playing during my "normal" time (Euro prime-time) and a bit later when probably activities in the US start, players seem to be different. There is not only a difference in numbers, but in play-styles. Numbers might be causing that change of style, but somehow I doubt it can explain it sufficiently. A lot more short-term players during those times of the day? That would somehow be consistent with recruiting targeted at those playing at peak times? What's the ratio of rank-0-players / total-players (or zero-star / total) at any given time of the day?
