I know is basically intended for games my question regards building an interactive app (flash or director like), is Unity good or suitable, any hints? Marchello
This isn't a good place for this question - too subjective. As per the FAQ, this really belongs in the forums. There are numerous posts asking about Unity's viability for this project or that project and with very little searching, they are easy to find.
It really depends on your definition of multimedia application, but the short answer is Yes, Unity is good for iPhone multimedia applications (look at the number released using Unity). Whether it is the ideal development platform for your specific multimedia app depends on what kind of app you are trying to develop.
I don't see why it wouldn't be - Unity is a very robust production platform. It really depends on what you are trying to achieve. Additionally, keep in mind that a lot of the iOS API features are not available out-of-the-box in Unity iPhone so there might call for manually bridging between Obj-C and Unity to access specific features.
Hope that helps.
