Landmarks were introduced in Sim City 3000, and although have been subject to a lot of criticism I think they're a good idea. However, I do think they should each have some purpose (i.e. they help your city in some way - even if it's just boost commerce slightly through tourism). I also think we should have to pay to build them - this would remove the need for a limit on the number of landmarks you could have in a city at the same time.

One suggested idea was to have some sort of landmark statistics window, which would show the amount of tourism (or whatever) that particular landmark is bringing into the city.

Ideas for other landmarks:

• Warner Brothers Studio in Burbank, Ca.
• Grithfic Park in Los Angeles, Ca.
• Belagio Hotel / Casino in Las Vegas, Nv.
• The Plaza Hotel in New York.
• Kennedy Space Centre
• Legoland
• The Millennium Dome, London, and The London Eye.
