Hi I used to have PS3 try mine. More participants the better.
First I have a very long one which utilises spread out but well placed check points where possible
Second I have a storm drain race that includes a bit of Down The Drain but much longer as involved BOTH drains
Thirdly I have one that simulates a family day out with a road journey where the navigator fakes you out ocasionally, a tiny bit of weird off road then an alternate return journey
if the links say PS4 at all just change to PS3 as they definitely appear in both searches
I used to try and make all my races lap races even when they were long so that the option was always there to increase length. So there is the odd weird design choice such as the beginning of the storm drain having to ramp over some water and change direction straight away...
