Hi. I have been working on a game for a year now. Recently, i found out that another game company is doing a game just like mine. The game being World Of Warplanes. Basically everything about my game is the same as World Of Warplanes, but i have not stolen any thing from them. Do i risk getting into legal issues if my game looks a lot like World Of Warplanes, even though i did not steal anything from them?
