The last few WVM updates are leaked beta builds, the full updates are increasing in size as he gains more support. The last full release was 800 renders for example. I would also say SL is more of a porn game than a story game, the story is fine but its obviously focused on the porn (harem, pregnancy etc.). I don't think its fair to compare others to Dr.Pinkcake or Philly games, those two are the best in the business.
Now to address the other posters question, I think it really comes down to quality of equipment and how much free time someone has to work on the game.
also,the tags need to be changed. They're only supposed to be for content that is currently in the game, not future stuff.
