Pros:

The settings
The activities
That wonderful feel you get from finally winning

Cons:

No real cons, but this is a definate challenge, and if you even have a single AI partner with 3 players, this becomes infinitely harder to beat.

Conclusion:

This review is actually of version 17 though. Looking at the changelog, what do you mean by: "Deleted all soundtracks and voices used in the map from the movie. I tried really hard to get the rights/permission for the music, but I can't do it alone."
I don't see how if you are not making a profit over this, you'd need permission to use this, being a fan project and whatnot. Or is there some other complicated shenanigans going on.
