body: Let's say there's Hyperion Cantos, a novel by Dan Simmons. I'm planning to use that novel's plot as a basis for my video-game plot/script.
  
  
  No character names or place names would be used (basically anything that could violate copyrights, etc). 
  
  
  Question is, how legal it is to re-use **ideas** from that novel in my video game? 
  
  
  (e.g. some fictional events/special abilities of a protagonist, basically everything that doesn't have name on it, but it has some properties/features that are related to original novel's fictional properties/features)
