I was in the CC community before I was here. I think any comparison of the two games is a little bit like comparing apples and oranges. Pretty much the only commonality is that they can both be classified as puzzle/thinking games (like appes and oranges are both fruit), but that's about it. That being said, CC indeed can be very fun and addictive, provided that you also download custom levels other people have made, in addition to the ones from the original game (which can be quite hard to find nowadays anyway). Like Lemmings, often the most interesting and fun levels are actually the custom levels fans have created over the years (I especially hate how towards the end of the original CC levels so many of them were mazes--not very creative.)
