Well, that's probably them trying to grow the market. It's fairly experimental, as d20 products go.
Like I said, I'm looking forward to it. Likely wouldn't use it out of the box with my current gaming group, but I've got one friend who would never do a standard D&D campaign who, based on what I told her, would pick this up in a second.
And from what I can tell, Ranger, they mean either/or. I mean, if you read Melanie Rawn and Mercedes Lackey and Tamora Pierce, there's always a love story in there somewhere. I couldn't run a non-comedic onscreen romance with my geek-buddies, but like I said, it could be a good way to introduce new people -- and, y'know, grow as a person and stuff.
