Why do I notice all the awesome threads like 10 billion years after they are created.

Sure, it was actually just 10 days. But still!

I have already finished the DS version twice, but what the heck. I want to participate in this, so I guess I can do it a 3rd time as well.

Question: am I allowed to play on a "New Game+", or do I have to start a "completely new game"?
