How much details and mechanics i could take without any problems (like: copying some idea etc)?. Ok so i want to make game (will call it X) and this game is inspired by other game( will call it Y). Ofc i am going to do my unique graphic, sounds etc etc but main thing that inspired me from game Y is how the "battle" is made, whole idea and mechanics in battle are so awesome that i want to do game with much more skills etc but with same CORE mechanics of the battle which i got from Y. I dont know if i will earn any money from my X game or anything, but i need to be sure that i can do it without any law problems. I can write that game Y inspired me ofc . How much i can take from mechanics from the game to avoid problems
Its like i would like to make very different game than Heroes 3 Might and Magic but the mechanics of battle are would be very similar(turn based, hexagons, etc) << its more less what i wanna do but ofc with other game than Heroes 3.
