Just finished up Monster Girl Quest Part 3. I really liked it.
Despite the 'rather extreme fetish', I thought that it had a really solid storyline with enjoyable characters that for most parts, has been quite well-developed over the course of the 3 games.
It does lack depth to its storytelling, what's with the contained town stories mostly having its setting, conflict, and resolution within the span of 15 minutes, but the ones that are given ample focus showcase what I felt to be an actual attempt to portray the conflicts and differences that can happen in MGQ's crazy setting. Many times the craziness of the whole thing is played straight for laughs and porn, but beneath them, there were clear attempts for the story and setting to have a real coherence of the good, bad, hilarious and dark sides of the universe.
And the storylines and characters that was actually given its time and due, imo, was quite good.
I would not consider toro to be a good writer, but Mac Walters could learn a thing or two from him.
