I know that collision may be a problem with pc, but I think its important to have for everything else, npc, mobs and even some environments.
I never said to put collision detection back on PC. I understand and agree.

However, collision detection can be a great way to feel like you are in the game.

Take the tall grasses for instance, it would imo help to breath life into this game if you were slightly slowed down when running through tall grasses.

It just needs to be implemented to be slight collision for things like grass, and more like 75% collision for things like mobs, that way you can still move past them but it would be an inconvienience, just like irl!!
