Arma 3 boasts a level of freedom and depth that no other games in its genre have matched yet. It is flexible enough that you can create and experience missions and stories in whichever era or style of warfare you like, from history to sci-fi, both scripted and unscripted. Better yet, a game mode called Zeus allows a D&D style game master to create an unscripted mission or story while players are experiencing and affecting its outcome in real time. What more could you ask for? Maybe a new engine...

I've been using this software for professional and personal work for a while now, and I can say without a shadow of doubt that it has all the tools you need to create whatever you want in the world of 3d art.
