I agree with the people agreeing on the collectables of appreciating the game more. I see it the same way as you guys.
@IntoGloryRide, I NEVER need armor since I own a Police Riot. When you get inside of it, it gives you FULL health and FULL armor the moment you sit down inside. So when I need armor I go to Trevor's Strip Club and sit inside of it for a moment and get full health/armor. It's cool, too, because his Strip Club parking spots are available to Michael and Franklin, too. I can use any character and use the vehicles I have parked behind there as Trevor saved!
