Because with the upcoming update it looks like travian is making some good moves with T4 (improving the game without changing it) I think it's time to provide some more. Here's my 4 step plan to getting more players in the game:
1. continue improvements to the GUI for modernisation without changing the game. Streamlining and removing the clunkiness of the game is key here.
2. mobile and tablet app - really important
3. advertise! Need something to compete with the Arnold schwatrzeneggar and that Nordic woman wargame apps. Need to complete 1 and 2 first otherwise people will look in and go "meh"
4. Improved tools for alliance management. The alliance forum is good, suggest expanding to have an alliance wiki as well. An alliance chat would be great but this is hard to develop (see kingdoms) so suggest partnering with e.g. skype to integrate the feature without having to worry about bugs.
