Well, looking at the other tools they're offering.
"The D&D Character Visualizer is client application that allows you to build the character you want to play, either for your D&D tabletop game or for your game on the D&D Game Table. You select your race, gender, class, and equipment, and this tool allows you to customize your character as you see fit. Once you've built a character you like, you can create a digital miniature of the character for the D&D Game Table or include a snapshot of the character on your D&D character record sheet."

That actually doesn't sound half bad really. I likely wouldn't buy a subscription myself, unless it was like $30 a year or something, in that case I might be willing to drop a bit of cash for it.
