Yep. You can still order these at Steak & Shake, but they aren’t on the menu. My friends and I used to get these on a crazy whim, up until my buddy’s first heart attack at 17 years old. They’re almost inedible. It’s kind of like eating a slab of cheesy beef casserole, bigger than your face.
The motorcycle mod and the mobile base truck mod on the New Vegas nexus were very promising, but they had some issues and were susceptible to crashes due to being script-heavy. You could even mount guns on the motorcycle! It really fit the wasteland aesthetic. However the environments were mostly made to be crossed on foot, and not by a vehicle which can only be perfectly flat and only move in straight lines. Definitely recommend.
