A friend and I are planning on pitching an idea to venture capitalists in a few weeks at SIEGE 2010. He is handling the business plan side of things and all those related questions so I only need technical questions here. What types of things should I be prepared to answer about our project?
For reference its an economic game for mobile platforms(targeting android to start with).
EDIT-CLARIFICATION: I am aware that they may be more interested in non-technical questions, but my friend is handling that end. I am mainly concerned with technical questions as he should be able to field most of the rest.
