Pros:

Like everyone else is saying, very nice flow to the maps. I play this one as much as I have the campaigns from the original game.

There is an equal variety of urban, suburban, and rural settings and the are all done well.

It didn't bother me when I got lost on these maps. I spent 20 years playing linear mapped games, so some maze-type element is always welcome. It's more thrilling and realistic.

Another plus for me on this is that there is usually a reward for going off the beaten path.

The settings lend themselves nicely to the events.

Cons:

I've never finished it. The finale always lags out on me for some reason when all of the tanks show up and I have to quit...every time...right at the absolute very end. 

Apparently this is not a common problem.

Conclusion:

The best user created campaign and I've pretty much played all of them on this site. I've fired this one up nearly as many times as I have "Dead Center" 

The only reason I rated this less than 100% is because I never have finished it.

Heaven Can Wait inspired me to actually register for this site and finally rate it. Thanks guys.
