No, you misunderstood it. I rendered 3,410 images in 5 weeks (35 days), although last week I almost didn't render anything since I focused on writing the last scenes (~11,000 words last week). There's still ~525 to render, that's the work for this week.
About the writing, I learned about NaNoWriMo some months ago, when a player told me about it and that his story there ended up being the seed for an AVN he is doing.
It's easier to continue a story you know where it is going, with characters that you know how they think and talk, than starting something from zero. The dialogues almost write themselves (no AI here) because the scenes and the characters call for some things to be said. Most of the time, I need to stop the MC from saying a long speech. Or Emma to go on a rant, or Martha to become too emotional.
I always have been a fast writer, with an average of ~650 words/day during the whole My Dorm development. The highest average with normal development (0.3 and 0.4.5 don't count) was 0.7A (835 words/day) and the lowest was 0.10A (335 words/day). Right now, 0.16 is at 843 words/day, but that number will decrease; I won't write more but some days will be spent in wrapping the update. It would be the fifth (normal) update with over 700 words/day if I publish it next Monday.
Not 4,000 this time. ~3,950.
The last two updates went beyond that:
0.14: 4,199 renders in 42 days (99.98 renders/day)
0.15: 4,487 renders in 45 days (99.71 renders/day)
If I publish 0.16 next Monday, it would be ~3,950 in 42 days (94,05 renders/day). I was eager to get to 100 renders/day being so near for two updates, but it wasn't possible without adding unneeded animations.
How? Sleeping very few hours, sacrificing some social life, and working on My Dorm every free minute I don't spend with my family or at my job. Oh, and having a dedicated rendering machine.
Technically, it can be considered The Matrix for the characters, right?
