3 out of 5 is still what I consider a good game. It's mainly a slow beginning that brings it down tbh, but it's far from the only AVN to suffer from that, and the fact that it's only v0.2 naturally means that many characters and storylines haven't gotten enough focus yet to bring the score up.
Most AVNs wouldn't have gotten higher than 3/5 until v0.4 or v0.5.
