Surprised to see that no one has mentioned this yet, but POHs are extremely dated. Moving from a main zone into your house winds up is pretty jarring because of how ancient and shitty the textures look now.
It's probably too much of a hassle (maybe not even worth it?) to revamp POHs as a whole, but getting some polish on the textures and skyboxes would be great. Being able to pick a consistent style of grass would also be nice.
