40 hour...and then?

Well, reading around the interweb i read "over 40 hour of entertainment" "not less of 40 hour" but a question is rising in my head: "after this 40 hours, what does happen?"

Someone says that you have to go premium otherwise your capital city has to be deleted, is that true? If it is, i'll stop immediately to play this game.

If someone could response my worries, i will be very gratefull. (i know that probably all the rumors are b***s**t but i want to be sure)

|||40 hours of new and unrepeating content, you can still play after 40 hours.|||40 hours is the estimated time it will take to complete the game (Get to max level). After 40 hours you can still play just like you could when your first started.
|||The game does not have a time limit. You can play for free as long as you want but after ~40 hours of puregame-playyou won't get any new quests. Of course f2p has other annoying limitations...|||Grind for 40 hours, thencontinue grinding (if that's fun for you) or play PvP.|||or upgrade to premium :D
