Are you sure you've been following him before? I've been following him since his RPGM days and he wasn't doing monthly releases then either. Also the amount of renders and animations per Milfy City updates is way more than what we got for Milf's Villa and Incest Story 2 which they were working on at the same time.
For example, Milfy City 0.5 was in production about 3+? months? That update had 800 renders and 60 animations.
Reminder they were working on Milf's Villa and Incest Story 2 at the same time.
- Incest Story2 0.1 was released beginning of Jan 2017, 0.2 was released around the end of April 2017. 3 months.
- Milf's Villa 0.2 was released around end of February 2017, 0.3 was released around end of May 2017. 3 months.
- Incest Story2 0.2 update had 205 renders and 32 animations
- Milf's Villa 0.3 had 175 renders and 11 animations
Combine both, that's 380 renders and 43 animations. Far less than what we're getting for Milfy City updates.
So, I'm confused where you are assuming he has become lazy and not working as hard as before.
