Im planning a "epilogue" adventure for an ongoing adventure im DMing rn, and I wanted to do a road trip like story structure, however im woried it would make the adventure too railroad, or just boring since it is an OGL system (Paranormal Order, brazilian system), does anyone have had a similar experience or have suggestions on how to make a game design that emulate the feeling of those kinds of movies without seeming too peacefull or boring since the premisse is to have more roleplay and less combat?
