Do you compete with you other parks you made, to see which park is the best: rides, attractions and other?
Yes,
I see which park can build the best rides.
i make bigger rides in each park to see if i can beat the other parks i'd made.
It more fun!!
I compete with the same park, going back and replaying the level to have a higher park rating or meet the goal sooner. I personally think the levels are too different to really compare them to each other, but so long as I'm doing well I don't really care!
