As far as re-packaged games go, Circus Empire is relatively new. It came out July of 2007, and by October it’s at the BFG site.

Gamezone did a review on this one, and it’s pretty favorable of it being a relatively easy to learn simulation game.

Circus Empire is a basic simulation on the lines of Zoo Tycoon or Rollercoaster Tycoon, but on a much smaller scale. This means there is less to do, but it also means it’s easier to play. For people looking for a few hours of easy entertainment that doesn’t require a lot of thinking, this is a good choice, especially for families with kids.

Sounds good to me.

There are really no demos available for this one. Not even on the Enlight official site. Here’s a link to a help forum in case you get stuck.
