Any expo worth its 'ex' (or indeed its 'po') has an award ceremony and GDC has bundles of them. The first one to get people all misty-eyed about opening envelopes however was the mobile division of the Independent Games Festival. (Please note that 'mobile' in this context is American for 'handheld'.)

And the winners were as follows...
