vee41 , I got that from the sales page here:
https://store.unity3d.com/
Here is quote from the unity FAQ:
Can we sell games and make money with the free version of Unity?
Yes you can create and sell a game with the free version of Unity, without paying royalties or any revenue share. However, the free version of Unity may not be licensed by a commercial entity with annual gross revenues (based on fiscal year) in excess of US$100,000, or by an educational, non-profit or government entity with an annual budget of over US$100,000.
Please also be aware that the feature set of the free version is not intended for the production of professional games and interactive content. Lastly, games made with our Pro trial licenses may not be distributed nor used for commercial purposes.
And here is another one from the download page:
The free version of Unity for Windows. Includes publishing support for iOS, Android, Windows Store, Windows Phone, BlackBerry, desktop and Web, and a 30 day trial of Unity Pro (with Pro publishing for iOS, Android, Windows Store, Windows Phone and BlackBerry).
And like said before, Unity has solid track record of high quality mobile games. With the new 2D tools becoming available soon it is something I do intent to check out. Nothing beats C2 in approachability though :)
