Being one of those long time players there is some questions...

What kind of incitaments is there to keep long time players to continue playing?

As it is now I have a serious over supply with nothing to spend it on and as there does not seem to be any influx of new players so how is the future of the game really? I find it ridiculous having an income of 50k gold/month and the most expensive to build cost the miniscule of a fraction of that sum. And with such income starting a war becomes obsolete very fast since you produce more in a day than whatever loot that you would get since no other players are that advanced yet and still playing.

Will there be any solution to this? Or is this the best we can get?

Well, we are trying to get new players to Mortia... would be funny a terrabellica with more active players. Worst games have more people playing them...
