Exactly my point. I've done renders that even utilizing a render farm took over 6 hours for one render. Granted those were much more detailed than what you have in your game, but I was also utilizing probably $50,000 USD worth of computers for a single render. I very much doubt you have that amount of computing power at your disposal. Assuming your have a similar amount of processing power available as I currently have, I wouldn't be surprised if a single render for an animation sequence took you between 6 and 7 hours with your current models, barring any inconsistencies in the final product.
The writing is something that I don't have any comparable experience with, as I am not a writer myself. However, I wouldn't be surprised at all if just the writing portion itself takes roughly a month or two to finish by itself.
People just need to learn to be patient. A finished product can only be as good as the amount of time spent creating it allows, and you can't rush things like this. Keep up the good work altosandherdone, and rest assured knowing that many of the people interested in your creation are more than willing to wait for a good update rather than a shitty one.
