Q: Can we use the code/art/assets in Unity Technologies’ example projects?

A: Yes, all assets in our tutorial and example projects may be used in both commercial and non-commercial use in Unity-based projects. The assets themselves may not be resold, however. Note that these assets are widely known in the games industry, so if you do use them in your titles it may be obvious that you re-used Unity assets.

Yes you can use standard assets ,even comerically. Have fun creating.
