Is it worth it?

I have Peggle and love it - am still working through the challenges. I downloaded the hour trial of Peggle Nights (all excited!) and as far as I can see it's exactly the same as the first Peggle. What do we get with Peggle Nights - is it really worth having? I thought there might have been different creatures or something!

There is a new character and the challenges are better, and more difficult. I love it

I never played the other ones, so I am really enjoying this game. Very addicting. It was well worth the club price for me.

I think there is only one other one. There will be a new one in a couple of months!
