Well, Inno could nave a "Non-Event" Event where they put up a quest icon that says, "work on your city for 2 weeks and we'll get back to you." Then they could have two buttons: "Decline" and "Okay." Decline skips the whole thing, the icon goes away and you get "silence" for two wonderful weeks! The "Okay" keeps the icon and after two weeks -- if you leave it on -- you get your just rewards: A 5 x 1 minute instants AND two weeks of uninterrupted building on your city! The latter is worth every non-minute you spent in that glorious 2 weeks doing the NOT-Event! And eve if you declined the "NOT-Event" quest, you'd still get the two glorious weeks of city building without interruption! Everybody winds and the participants win only slightly more than the non-participants, which, generally given the value of the prizes, is about right!
In the end Inno would actually make some dough on the matter as the break from the constant stream of Events, tournaments, Fellowship Adventures and mini-events, and the sudden upsurge in city-building might reenergize more than a few players.
Well, that's just a thought, of course.
