Yet to be seen. I doubt it's a direct "copy" per se (it'd have to be copies of someone else's work, I doubt she could figure out how I code mine being how it's so dynamic in structure) but it's the point of being knifed in the back (possibly) like the GS AVN recently. I'm hopefully just gun shy, but it smells really fishy. We'll see.
Just so folks don't get the wrong idea, I'm not opposed to devs advancing their coding knowledge and adding features over time as they have predetermined best for their project. Hell, I collaborate with a few dev teams (in private) to do so. But there's a real difference when a dev obviously takes a rather large timeout during their story development (VN story updates) to "create" the aforementioned feature sets in mass quantity all at once which is almost always a blatant ripoff of someone else's ideas and/or work.
I could go on into further detail but would rather wait for this to play out and see where I stand. We'll all know soon enough I reckon.
