Yup, thats my plan ;-)
Ok, I absolutely love your idea, but in order for it to work we will need much more than 15 mins. More stalking, hunting and being picky about which pray to attack will simply require more time.
When I play a quick hunt as pred, for me at least, its like the last 15 mins of a new predator movie – stalking and hunting is over at this stage, its been going on for the last (unseen) 1.5 hour. Now its just fast pace chase and brutal, screaming murder.
I personally think that your idea would make this game a completely new experience, but we would need the match to last at least 30 mins. At least….
