It's quite a good review. I'm not sure about it not appealing to anybody who has not already had exposure to Magnamund. Maybe I'm just a deluded fan boy, ok, ok, but I think that RPG stands very well on it's own merit. The classes for example are superb well detailed with a really nice range of abilities and the world description is also very good.
I'm using the game at the moment as an introduction to RPG's for my kids. I'm also planning on using it with a group of adult friends. It's great as an introduction, but it is so colourful and characterful it will be great fun for veteran gamers too. At the very least it should appeal to people that are new to RPGs but not Lone Wolf fans, with the free game books to back it up it's got to be one of the best intoductions to RPGs out there.
