Git Gud 030 - Traffic on your roads!
If you have roads in your park, they might look a bit empty.. Or sometimes I see people park stationary cars on them. It's much nicer to have some cars actually driving on your road! Thankfully, in OpenRCT2, this is not too difficult to do! You can simply give a car ride an invisible track, put some chainlift on it at a higher speed, and put the ride in test mode! I personally also like to open the ride, to make sure the cars have guests in them!
