According to Naughty Dog, the season pass for The Last of Us will apply some tweaks (called "bonuses") to give you an advantage in the campaign. They allow you to reload faster, heal faster etc. I really think season passes are a good value if you plan on sticking with a game, but to give you weird little boosts like that seems like it could undermine some of the design of the game.
So I've got two questions:
First, is there any good reason to use "bonuses" like this on initial playthrough?
Second, I haven't really encountered this specific scenario on a ps3 before so I am wondering how easy it will be to not apply the season pass if I don't want those bonuses. I know for some 360 games I have just deleted the download and re-downloaded in later but I'm not sure how that works with psn.
