I Do prefer collision but i'm not going to care its gone.
My issue is the lifeless npc's/mobs.. The world looks so vibrant, but its so empty at the same time.

Everything just stands in place like a statue, would it be so bad to have npcs wander back and 4th?.
For the mobs things like sheep following each other, they could group up, when a player runs at them they scatter so you can pick one off, pick one to close to the others and well they all jump in on you.
Some of the the aggressive animals attacking others around it if they get to close?

And now after seeing the massively oversized mice, we could do with critters wandering around, just to give the maps a perspective again. (or just put in the mobs the same size they were before or at 0.75 smaller but at Lv0 with no loot table).
