Yeah I have a Mega ADK that I use just fine with a bread board. I was building this a) for soldering practice and b) to build the finalised version of my project on.
I just expected the kit to have a specific "completed form" that they expect you to take it to before you start building. The fact it has clear space for two LEDs and two resistors but comes with 3 types of each is a little odd to me.
