Now that you guys did the right thang and locked everyone's flags to IP geolocations, would like to see it utilized through some other features if at all possible. Didn't think for super long, but was able to come up with one idea.
As the game becomes more international, maybe it'd be nice to have a "same country" or (even more narrowly) "same language" indicator. The latter would require some separate database that categorizes countries by language.
I don't know how taxing that'd be on the server, but if significant then you could disable it for US and UK players (since they probably account for the large percentage of the playerbase).
Maybe the indicator could be a flag over players' heads. It might be nice to have it on by default for new players from less popular countries, as it could help them get around a bit easier. I just think maybe it'd be helpful for new players to find other players who speak their same language and for regular players to find new people to socialize with.
For a long time, French-speaking players have gathered to the right of Azrael's and Spanish-speaking players have gathered under the GC bridge. I've more recently noticed Arabic-speaking players start to come around the left side of the GC restaurant. I think it's obvious that players would like to be around people from their same country, same language, so this could help.
Post ideas, etc.
