But that doesn't mean you can just take someone else's idea, split it apart, and make it again in another engine.
There's something called intellectual property rights. If you can't get an idea yourself, maybe stay away from making games.
Or better yet, be inventive and come up with something yourself, do the renders, maybe that will be interesting.
PS: Unity is a much more useful engine than that old crap built on top of another 13 year old game engine. Leave the original alone.
