In my opinion, it would be better to just give a restriction of 10 attractions (or whatever the limit is) rather than give restrictions for each ride types. That way contestants can still make things such as duelling or racing coasters. 

Some other things to consider in future:

- Everyone should have access to zero clearances, as at the minute some people are having to rely on mods and I think that's an unfair disadvantage. 

- The self-sustaining area criteria for the judging should be reconsidered as I think this will be quite restrictive when contestants are working with attraction limits.

As for contest ideas, a theming contest could be considered, where contestants are given the same layout of a coaster or other track ride and then have to theme it and make it into a park area. Someone also suggested a duo/partner/team contest where contestants compete in twos or teams on each area.
