I was really excited about this product as I enjoy solo gaming, especially of the RPG kind, but there are very few options out there for such gaming.
Sadly, Avalon Quests feels unpolished to a point where it's uncomfortable to read through and use as reference.
Mostly, my qualms are with the layout and organization of the rulebook and the travel book which make it rather hard to understand how things work. For example, the travel book references "Sections" multiple times, but these are not indicated. If you read everything, you can guess at which paragraph they begin, but having to do that isn't normal.
The use of roman and arabic numerals to refer to the adventure or rules books is commendable, but remained confusing to me. Various typos do not help. The night encounters section is a blatant copy/paste of the day encounters, down to the table number being the same. As such, tables 3.3, 3.3.1 and 3.4 are noted 2.2 and so on.
Ultimately, it's a mess, and while I have been prodding at this in the hopes of getting some solo gaming going, I find myself exhausted and frustrated before I even start. Today I decided I wouldn't even think of trying this for a long while.
Other things of note about this product:
The adventure provided requires 6 PCs. I find this to be too much. Soloing is not easy to begin with and while I have played one-on-one games controlling 4 PCs, I can't imagine doing it with 6, especially without a GM to catch my mistakes. It might be worth trying a multi-player yet GM-less game with such a party though.
Art is really subpart, though tactical maps are provided for various encounters.
- There is a lot of content, whether random region events or adventure specific encounters and quests, which makes it even more frustrating that I feel I can't get to it in a comfortable fashion.
Overall, there is a lot of potential here, but right now, it's a rough stone ripped off the wall and it's in need of some serious cutting and polishing before it can become pleasant to play.
