- except you cant make a case for those two games being plagiarized from Blade Runner. Plagiarism has distinct judicial meaning and it would not be applicable in case with works of fiction like that. First and foremost, its two different type of media. Secondly, who even gonna bother? Scott? Villeneuve? Dick's relatives? Warners/Sony? And while we here, should bethesda/microsoft be scared too because of Fallout 4? Lets be realistic, not everyone is a mariomon company.
In case with video games all AAA segment are essentially kissing cousins, those games resemble eachother while being produced by completely different teams, working on different companies. And no one sues anyone.
In videogames in general, being influenced by something to the point of almost resembling original is absolutely normal. Remember RTS craze of nineties? Isometric RPG revival of 10's? etc etc
Successful movies constantly spawn numerous impersonation movies, yet no one sues anyone. Big releases constantly followed by cheap knock offs, yet no lawsuits.
Even in popular literature you can see this trend. Just look at YA segment. All those YA novels arent even kissing cousins, its an outright full sibling orgy ( no step bullshit there ). Yet, they all getting published and no one sues everyone. Okay. One person tries, but he fails constantly - Michael Murcock. For a hard lefty, he does love his copyrights and loves to apply them rather frivolously - "Oh look! That guy has a sword and white hair! It was stolen from me!".
