Hello, remember that you're consistently wonderful (I was going to say hello at some point anyway but that cheesy Headman pun compelled me to come before I get back to work :b ).
And also, if you want to give some spooky, interesting, obscure games a go (or at least add them to the Play Someday pile!), I'd heartily recommend CLASSIC GAME (by iamqqqqqqq) and the Pagan trilogy: Technopolis, Emporium, and Autogeny!
Can't say for sure, especially since AI Gigapixel has changed a lot since then, but currently I usually start with 6x resolution, Face Refinement Off, Supress Noise 0, Remove Blur 0. That usually gives a pretty interesting starting point. After that, I might open it in Topaz Sharpen AI to give it a little boost, and then proceed to get some filters going in Topaz Studio 2 or Adjust AI. Having more interesting layers to work with helps when I open everything I've created so far in Photoshop, and pick and choose and blend as I wish. Once I choose a direction, I begin touching up by hand or using the tools in PS to fix it up.
