Re: Campaign Cartographer 3
I have it. The interface is a nightmare.
Yep. I've tried some of the various options out there and none seem to be much better. Autorealm comes close. It's freeware, but hasn't been touched in years (someone is rewriting it though). It's also pretty difficult and in my experience rather unstable. If you're not sure how much you're going to use it, I'd start there and see if it's worth $40 for something that may only offer features you won't use and may not add much you don't already have.
I can't speak for it now as it's been years since I've been involved, but http://www.cartographersguild.com/
used to have a number of excellent tutorials and a helpful community. They aren't specific to any one of them (some of the best work I've seen there is straight photoshop/gimp). Their forum has a section discussing the various options, and they can give better pros and cons than I can.
