Global Game Jam starting in a few hours

I’m looking forward to participating in the Global Game Jam this year, which will start in just a few hours. This will be my first GGJ since last year I signed up too late. I have participated in numerous 48 hour competitions in the past so I know how difficult it is to create a game in such a short timespan. My plan this time is to get the essential experience prototyped as quickly as possible to evaluate if the idea is actually fun. I have in the past wasted too much time on ideas that weren’t fun and ended up starting over. I haven’t decided if I want to use XNA or Unity 3D but I’m leaning more towards Unity.
