Sure, it's a creative process, no one is denying that part, however to say that getting hired help for at least posing/making renders makes the development of the game "boring and tedious" is just unreasonable, it doesn't limit creativity in any way as long as you're still the only person making the final decisions on how a scene looks and feels (wow, communication!).Here we go again.
The amount of work DPC puts out in a single release is more than just about any other dev puts out in x number of releases in the same timespan.
One can argue that the story can be planned and written in such a way so as to chop up a single release into 2, maybe even 3 releases. That is a valid argument. (For the record, I'm firmly in this camp.)
And the fact that you think the "perfectionist" argument is flawed is very indicative of how you don't understand what is involved in creating a game. Anybody who thinks hiring more people will make things go faster has no clue how project management works. You are simply trading in a creative process (something DPC enjoys) for a boring and tedious process (something DPC doesn't enjoy at all).
What one can't legitimately say is that this is a milking issue. What it is, is a bunch of crybabies that think the world revolves around them and they are entitled to get what they want when they want it issue.
When implemented in such a way, the dev can use less of his development time and attention on rendering/posing/modeling/animating and instead focus on things such as writing/coding/branching etc. And i agree with you on the fact that project management can really make development tedious, BUT for that to happen you need to have 2+ people to manage, which would be overkill in this case.
What this is a case of, is the dev being overly comfortable with the fact that his supporters won't leave him (which would be good if he was actually TRYING to optimize his game development time). Don't get me wrong, I understand that keeping creative freedom is crucial in developing a game as good and as big as this one, I, however, do NOT understand when even the slightest attempt at sacrificing your own comfort ( and that's exactly what this is, *comfort*, not creative freedom) comes at the cost of increasing times between updates to ludicrous amounts.
