Hi,
I suppose this might be a bit out of the current scope, but IMHO a Travian-like collaborative endgame with the reset that follows would really make the game interesting.
To be a bit more specific, I am referring to the construction of the "World Wonder" type of structure, which, upon completion, would mean victory for the owning clan/group and then the server is subsequently reset.
In addition to the current gameplay of maximizing individual infrastructure/utility, this would add an extra dimension of inter-player logistics and role specializations (e.g. the players that defend against the other clans or the farmers that contribute resource to the builders). The reset that follows would mean that the game is periodically made more accessible to new players.
Thanks for making such a great game!
