I went ahead and downloaded it, just to prove you wrong. 782 images + 400 images = 1200 combined for the last 11 updates.
He's on Chapter 11?
I'm on Chapter 7 Part 1, my Chapter 6 and Chapter 7 Part I combined have ~1000 images. Part II will have anywhere between 800 - 1000 added CG's, meaning one of my chapters will be bigger than his 11 chapters. Again, not throwing hate, just stating facts. So saying every update is much bigger and cheaper is just wrong. You would've paid more for his 11 updates, even though, they come out a lot faster, they're also a lot smaller.
And sure, his progression is further and a lot faster. I spent more time building out a proper narrative, so when you get to those scenes, they feel earned and not rushed into.
Different strokes for different folks. If you enjoy his game more, by all means, you're happy to do so. I've been a subscriber to him for the last 10 months. Do I play his game? No, I don't have time, but he clearly puts in the work and deserves support.
In total, SoA has 2.6k images at this point.
