Hey, I'm happy to hear you enjoyed this. One of my main inspirations for this was Fallout 3. When it first came out, I was hopelessly addicted. It made me vow to never own a gaming system. I don't know what heroin feels like, but I always thought it'd be a bit like Fallout 3.
I wanted to write about a game that was like fallout, but completely immersive. Bioshock isn't that far off either. That was a really good game too. Same sort of palette.
