Bill,
PG plays well solo, unless Pacific warfare is your bag I would not start with Guadalcanel. Elsenborn Ridge is excellent module to start with IMHO
Its strange that I enjoy solo play as much as FtF but both are very different experiences. I rate games on balance, fun and content. Even if a game is fun and balanced it will lose rating marks from me if I have to finish developing the scenario during play (ex AK33) or their are ambiguous special rules (eg SF22). Also if I lose in a FtF the scenario may lose another point (hence my rather low average rating in FtF games)
