I'm using my experience playing RoH as inspiration for a book I'm writing about a young guy who has to solve a real murder by logging into an underground MMO to finding the killer.

I don't want to make a RoH fanfiction, or lift any content that's owned by the people who've contributed to RoH for the lat twenty years. And I'm trying to figure out how much I can use as inspiration, without crossing a line where I get sued by Ocelot.

Do you guys have any advice for me for what's fair to use, and what's not? I'm thinking I can change the names and the lore, but keep the spirit alive of playing Realms of Hell back in the day. I've decided to call it Abaddon Online, and called the starting city Bridgeport. Yeah, I'm really reaching, I know.

Feel free to use any of my chars, as long as I get partial credit
