I’m not sure. That’s the first I’ve heard of a fire. It’s pretty easy to find in my area, but I can’t speak for the rest of the country. I have noticed the price go up some in recent years, but I assumed it was from popularity and just general inflation.
I had a similar experience with Dishonored. I got ghost on a few missions since low chaos is more akin to my natural play style, but found it to be more enjoyable to set my own “rules” for my playthrough. It’s also a game that’s worth a second playthrough just to experience the opposite side of the spectrum. Super fun game any direction you choose, but you’ll miss a lot of cool aspects by limiting yourself to one extreme or the other.
