Ask the expert: Andrew Smith

Thanks to everyone out there who sent a game design question for our resident expert, Andrew Smith - co-creator of iPhone hit Hard Lines and designer on the team behind the BAFTA-winning Flock! for Xbox 360.

We were bowled over by the number of qustions we received, with topics including how to make a memorable baddie, the best way to smash through creative block, and how to add extra downloadable content (also known as 'DLC') to extend the life of your game.

Check out the video above to see Andrew's answers to these questions and many more - and, of course, to see who's won the coveted prize for best question!
