Truer words have never been spoken. But I actually do agree with him.
7 chapters of build-up (a good one, by the way, along with the story) with barely any lewd...ity with Avalon. As well, I'm not throwing any hate, it's just creating some high expectations related to the main girl (which we can afford to say that 99% of the ones playing it were fond of) and then throw a hot redhead sister through the end, and then...
If Penny will be the protagonist on the next game, that's dev's decision alone. But that doesn't mean that we don't deserve (care lightly that I don't mean it in a negative way) at least 2 or 3 chapters of good/lewd content with Avalon before the game is marked completed.
