Did you ever think on launching travian on steam ? like the tribal wars just did? I bet the population would grow drastically which is crucial to the game or it will be dead in 3 years...
On the other hand, your servers are already buggy and lagging every time a new one starts and it doesnt even have more than 1000 players online at-a-time so you would also have to invest in the game which we know you WILL NOT, plus you would have to share income with steam i guess
the question then maybe is do you want people to play it or squeeze the max out of us before you can focus on other games
anyway, just a thought gl & hf
