I'm not sure if anyone else has posted about this, but I tried looking through the forums.
I don't think that each district (Groddle Forest, Alakol, Shimla Mirch, etc) has enough "connection" between its players. If we had a community center, or "hall", I think this would improve. We might be able to play certain games with each other, or do certain actions.. Community-only gardens of sorts.. anything, but limited to those specific residents.
Such things could be added.. like for example.. Alakol Banks, Groddle Forest Police Station (lol), or whatever :)
It would especially help out the groups already made for each area!
