I really love the idea of the Hunger Games from the Hunger Games series. I don't mean the EXACT formatting per se, that is, people randomly chosen and pitted against each other with only one survivor at the end. I DO, however, like the fact that the Hunger Games are the stage where humanity/the characters show their true worth and character; their development, by pitting them all against each other. I like that concept. My question is: if I choose to use this idea of pitting my characters/protagonists in a situation like the Hunger Games or something similar, would it be plagiarism, and could I get sued? Note: they won't be necessarily pitted against each other, if you're wondering. It'll basically be kind of the "arena" aspect of the Hunger Games, with everyone watching (just like in the Hunger Games when people can see the games on TV and stuff, except I obviously won't be copying that part from the Hunger Games). If I decide to use this aspect of the Hunger Games for inspiration for my work, would I get into any kind of legal trouble? I just want to stay clear of all that. I mean, I naturally love the premise of the Games and all, but I don't want to come off as a copy. It's unfortunate that I couldn't be the 'Suzanne Collins' before she used the idea in her series (although Battle Royale preceded her and is also similar...). Note: I obviously don't have characters named Katniss or Peeta, etc etc. Nor do I call my "Hunger Games" the Hunger Games. I do keep the "selection process" aspect, and the "arena" aspect, and also the "pitting of someone or something against ______" aspect.
