[QUOTE=gonzdevour]Unity is a great cross-platform mobile tool; however,
you need not only coding skills, but lots of money. Engine has a price, each function has a price, each exporter has a price[/QUOTE]
The standard version of Unity 3D is free, and both Android and iOS standard exporters are free also until April 8.
But I agree that it's really a different beast than C2. C2 allows you to really make a working game on the first day you pick up the software. It's not just a marketing claim, but actually true. It even scales well with the user's knowledge and much can be done with it as far as HTML5 games are concerned.
Unity has a much, much steeper learning curve. It's an awesome piece of software too, but purpose and audience are quite different. It's not better, or worse, just totally different.
