Hello everyone and thanks for taking the time to read this post. I just have a fast question I'm not able to answer for one of my friends, and one I'm having trouble finding the answer for on my own. I'm pretty sure its a copyright issue. At any rate(and I've considered this but, steered clear for seemingly obvious reasons)she wants to base her book off of a video game. A rather successful one called the Last of Us. I warned her off of the idea simply because better safe than sorry, something I deduced for myself years ago. She wants to base it around different characters, separate story line etc. just in the same world. Now correct me if I'm wrong but, even if she didn't name or connect the book directly with the Last of Us couldn't(and wouldn't)good ol'Naughty D pull copyright? I've seen stuff like this done before I guess but, it still seems legally unsafe. At any rate thank you guys for your time and I look forward to any answers.
