Creative Cloud - the Publisher's Best Friend

If you're thinking about publishing role playing game content and you can possibly afford it, go get an Adobe Creative Cloud subscription. Period. Yes, it's $50/month or so, but look at what you get - not only do you get InDesign for layout and Photoshop and Illustrator for art, you also get Dreamweaver and Muse for web design, Audition and Premiere Pro for making videos of your work, even animation and rendering tools. Best of all, they all work together. It's certainly possible to cobble together an alternative set of freeware/shareware tools that do all of these things, but not as seamlessly as the Adobe suite. Totally worth it, every penny.
