That's quite an amazing tool. The major plus is that you don't need any programmers/engineers to develop your engine/features, it's extremely easy to set up (albeit you need to have some knowledge of 3D engines in general) and you can produce some great scenes in a handful of hours.
Download some of the demos (they hold a yearly contest). I'm sure you'll be surprised by the results.
