separate from throwing it. 90% of the potential interactivity of a grenade is collapsed when it explodes
in a game where you can throw a grenade without pulling the pin
-force enemies to break cover, unaware grenade is not live
-dialogue opportunities when they realise
-a free "throw distraction" verb without adding a system
-shootable non-live grenade doubles as remote bomb
-can throw one in somebody's face, stunning and freakin' em out
-share grenades with pals
-risk/reward, enemies can pick em up. "hey free grenade"
-enemies approach non-exploded thrown grenades tentatively, because throwing a non-live grenade is a weird thing to do. what if it's just defective
-if you do this too much they start expecting it and getting cocky about your grenades, with hilarious consequences
as long as i am only throwing a grenade to flush somebody out of cover, why waste it. foolishness
