When I was playing dying light with friend we discovered that every timw you go to sleep and wake up air drop will appear, if you don’t know air drops are pretty rare and if you collext them and deliver to one guy you will recieve lots of xp, we used that multiple times to unlock grapling hook very early. Air drops also gave lots of medicine which was hard to get in early game and that very helped us
In Sonic R, there’s a track with an explicit “trap hole”, and a long winding path to climb back up. If you just don’t climb back up and explore the map, you’ll find yourself back at the track’s beginning, and it’ll count as a full lap. Cuts the laptime in half.
