Already a fan of their work, I was pleased to learn that The Forge Studios had been picked to illustrate Ptolus: Monte Cook's City By The Spire. I believe this was an excellent choice. In the Ptolus Sketchbook Vol. 1: Midtown, The Forge Studios get to do what they do best - to help create the unique architectural look and feel for that setting. The importance of illustrations (and illustrators) is often overlooked by gamers, but their work is invaluable as visiual aids when it comes to setting the tone of a setting or location in a game. I'm certainly looking forward to the future installments in this series of products.<br><br> <b>LIKED</b>: Arguably the best work from The Forge Studios to date. You can tell that the artists have a background in architecture and a good sense of credible fantasy settings. Also, the art in this product is generic enough to be used for any fantasy setting, whether your are planning to use Ptolus or not.<br><br><b>DISLIKED</b>: Some might have preferred the Ptolus Sketchbook as an art pack of jpeg images rather than a PDF, but for me personally that's not a problem. Ultimately, the usefulfulness of this product is only limited by your own taste and style in gaming.<br><br><b>QUALITY</b>: Excellent<br><br><b>VALUE</b>: Very Satisfied<br>
