cant remember much since i havent played it.. but high intensity comes from goin around a sharp turn at a really high speed or a loop at really fast speed.. or doin anything like corkscrews and stuff at really high speeds if your gonna have those sortsa things in your park dont make it so it goes through them REALLY fast.. make it go through slowly.. You have to make sure the excitement is queit a bit higher than the intensity on the ride..
Dont do anything fast accept a straight away actually

... like.. ugh.. for example.. have a ride go up pretty high.. then make your big drop.. then go back up a hill to lose some speed.. then around a really wide turn and back down a pretty small hill.. not all the way to the ground then you can do like a loop or whatever at a pretty low speed and the intensity wont go up to much from that... i remember i was tryin to build a ride with huge intensity and i got it up to like 39 or so...
