This.
Probably an unpopular opinion, but I think the game has gone downhill since A15. In A15, we had hub cities and zombies roaming around everywhere so it felt alive. Then when they added sleepers in A16, it felt a bit empty because half the zombies were hiding in closets. It seems like every alpha since, they have been adding more and more into closets and less and less outside, so it just feels like a ghost town now.
The other day, I fired up the A15 alpha and it was thrilling. Knowing there's no sleepers, you don't know when you're going to go around the corner and walk into a zombie who is AWAKE and ready to end you. You can't just sneak around one-shotting all the sleeping zombies like you can now.
Of course A15 also had other great stuff as well like learn by doing, lootable corpses, smell, gun parts, the wellness system. What a gloriously close to perfect alpha that was. All they had to do was add more stuff, pretty up the UI, and fix the player models, and it would have been bliss.
Since then it feels like the Fun Pimps Police just take away options to funnel people into how they think the game must be played.
