Careful? Nah, I'm the YOLO-kind of guy, tho I'll try make it today, and hopefully they'll be fine with it ^^
Old ideas, new ideas - they are all the same, until one finally gets around to realize them :3
And if you are so full of terraining ideas, it'd be stupid not to go realize them! And not having much time, is simply a bad excuse for being lazy - get to it! :b
