Great at first... then...

In the first 3 hours that I had it I thought it was really awesome. I have the original gameboy advance version warioware inc and it was a definite improvement in terms of the number of minigames available. However, after I'd completed the story in a few hours, i didn't know what to do. I have 5 people in my family but we only occasionally play it together. And whenever i do have friends round, we never want to play it cus it's just a novelty really. Does anyone else have it??
