It's definately different but if you're coming from the Director/Flash direction you're already familiar with that. I don't see it as a downside structuring my code that way but i also don't like the languages which are supported in Unity, the poor documentation on them etc. A problem is that the fanboys don't really help enhancing the situation because they hooray everything and so it doesn't get improved. But well, i guess each product/forum has these problems. Seeing things grey never was popular.
