Greetings... I can't make my game an original one, as i'm not good at programming, i can't even mess up with code making something original! because there is something related to "vulnerability..." That's why i'm making my game an original game that uses the most notable original material of another game... it's like using a sound effect from another game knowing that it's used on that game and not something else, right? Wait! if i use something copyrighted on my creations... i don't need to claim as my own... just put something on the credits such as "Based of (The other game)"? and "Sound effects by (Original Creator)"? Or something else? I won't publish my game on Steam, but i'll publish it on social media instead... isn't commercial use? Also, no permission required because is hard?
