I was still a regular reader of TBP when Blue Rose came out, and there were plenty of critics there as well.
I was one of them. My personal objection was not so much the fact that the game's setting took a clear stance on the "correct" sexual morality of its universe -- as has been noted, this is part and parcel of the romantic fantasy genre, and anyone who knows the source material can plead no right to surprise about that -- but the degree to which the game material tended to browbeat you with it. As quoted in Dan Davenport's original review of the game:
"
Blue Rose is very,
very much about the acceptance of alternative sexual preferences. If this were simply a side-note to the setting as a whole, it really wouldn’t warrant mentioning; however,
Blue Rose beats the reader over the head with its message of tolerance to the point of being cloying: a major god has a young male god as his gay lover and is the patron of gay couples, a mother in the game fiction prays that this god watch over her gay son and his lover, fully half of all Sea-Folk are gay, clothing styles are fully androgynous, and so on. Conversely, conservative religious values (represented by the Jarzoni) are objectively closed-minded and bad."
It's worth remembering that the game was originally published in 2005, ten years before
Obergefell (we will pause a moment here for anyone who, like me, now abruptly feels depressingly old), so there's a certain earnestness to its advocacy that has suffered for being a little outdated since.
A more game-relevant criticism was that, again in keeping with the original source fantasy genre, the entire style and atmosphere of the game tended to exclude some of the most popular gaming PC tropes: Aldea was not a world where characters like Conan, Fafhrd and the Gray Mouser, or Drizzt Do'Urden could prosper much, because the stories of romantic fantasy tend to be highly character-centred and focused on personal growth through building relationships and nonviolent conflict resolution, with the action-adventure quotient being a distinctly secondary element at best. There's clearly been enough of a market for this for the game to stay in print, but gamers not familiar with the source material can be frustrated by the deliberate shift in focus.
