I'm a little skeptical of the idea of a solo RPG (without a GM/DM), and the low quality of this preview doesn't reassure me.
The PDF includes (1) a list of contacts and informants, each with a few prerequisites and available missions; (2) a map of "Hero City"; (3) a two-page adventure; and (4) two sample characters.
The text is full of punctuation errors, erratic capitalization, and other errors. The book opens with a comma splice: "Want to play a super hero RPG, but have no one around to game with, well Avalon is here to save you from your boredom." The introduction has further problems: "If you don't not have the listed ally or contact you may not take mission from that contact. You must also meat all listed prerequisites to take on the missions listed."; "It's a new century and that's calls for a new type of hero."
The sample adventure is a generic "rescue the kidnapped rich guy" thing for a brand-new character. As a preview, this adventure doesn't make me want to check out the full game. If there were signs of an intriguing overall plot, I might be willing to overlook all the textual errors. But instead this is strike two.
Since there's no GM, the narrative of the adventure includes branch points based on PC choices or skill checks. The text is formatted as ordinary paragraphs; it would be easier to work with these branch points if they (and the points they lead to) were marked. I can imagine marginal symbols: "If your skill check was successful, go to marker A. If not, go to marker D."
