@JubalBarca @killyourfm Second this! A game is not just a cool idea. Actually a lot of great games are pretty unimaginative. What matters is great execution! And that is extremely hard to do, thus also really hard to steal.
It's also worth mentioning that a LOT of game ideas sound cool at first, but work terrible in practice! I'd compare it to drawing: It's fairly easy to imagine something cool in your head, but significantly harder to put that vision on paper!
