I love your motorcycle-riding goblins, zombies, etc. and the concept of a genre-agnostic interdimensional apocalyptic road trip on sentient motorcycles. Petrol as an essential resource to be rationed and then refueled is a cool take; Resources seem to be a place where a lot of innovation is happening. At first I didn't realize the petrol gauges on the character sheets were intended to track Petrol, and was confused because I couldn't figure out where it said how much Petrol you get. I like the contrast between the PCs as a whole having a shared Formation ability and each different Rider reacting to Bliss and Road Rage in different ways; having everyone have a degree of control over Formation while players have essentially no control over their own Bliss and Road Rage abilities is an interesting choice, and I think I'd have to play with it to know how I feel. Also, the table of petrol station encounters? Amazing.
