I like that it's very easy for beginners (like me) who are not familiar with Unity3D or C# programming language at all to use this software without any problems because everything can be done using drag-and-drop method. It also has great tutorials which will help you get started quickly if needed. The only thing i dislike about test unity is its price but considering how powerful it actually is in terms of features, this shouldn't really bother anyone. If your looking into creating some simple games then definitely try out this product as there isn't much else available right now. Creating basic 3d game prototypes with 2d assets made from Photoshop/Illustrator files.
