[Suggestions] Improvements for the game

I'd like to see scenarios that could be purchased for sim cash, keys and money. Depending on the difficulty of the scenario would dictate the purchasing value.

Scenario examples;  

A ZOMBIE INVASION. Once the scenario is purchased and is activated the city would be transformed into a city with no power and plant life growth over the buildings.... etc. no more cars and the people if a zombie are bright green and chase regular people in packs. During the scenario you must save a certain number of pop-up sim city people from becoming zombies. Anytime a sim pop up graphic appears, you must save them from becoming a zombie. To save the pop-up sims you must build unique survival items like guns, bats, first aid kits... etc. These can be built only during when the scenario is active in police, hospital and fire stations. If at the end of the set time of the scenario you saved a certain amount of pop-up Sims you win prizes. Oh and if your pop-up sim becomes a zombie it stays a zombie throughout the rest of the scenario. You'll be unable to do whatever that pop-up sim did. For example sell items, preform tasks... etc. Scenario runs for 3 days or so.

Where IS MAXISMAN? Just like where is Waldo but SimCity build it style. Tiny MaxisMann are randomly spawned in your city. You have a certain amount of time to find them all. Depending on the number you find gives you prizes.

I'd like to see unique buildings for prizes. Also each scenario can be purchased for play unlimited amount of times.
