I actually like Max the porn kingpin, acting in movies and helping do cam shows. In fact, my ideal version of this game would involve the player making a number of choices/doing a number of quests for upcoming movies and earning money based on the outcomes (for example, whether you can convince one of the girls to eat another out, that sort of thing).As much as I hate Eric's guts, I have a feeling this game would be much better if he was the protagonist.
But as for Eric, I wish there was a 'cooperate with Eric on equal terms' mode where you and Eric share the women of the house. You'd be able to have a lot more variety, a lot more scenes, and you could use him to make better movies.
