It's all about giving the level designer more tools, more options. It's not like they had to pick one or the other.How does that make it a good idea? The fact that monsters started hunting for you if they heard you was a cool feature that's missing in a lot of shooters even today.
I think at this point if you don't get it then just don't worry about it, man. Over and out.
And just to be more on topic: ummmm. Bloodbowl 2 is 60% off. I haven't played it. Who cares. People can look at the Steam sales tab, this thread is kinda pointless.
Protip: put games on your Wishlist and you'll get an alert when they're on sale!
