I must be crazy, but I always really enjoy finding all of them in games like this. Pretty much the first, and often only 'collectible' (not sure what other category they'd fall under) I complete. Assassin's Creed is another series that makes me rush around the map to get them.



Guess I just enjoy exploration and the nice view of the area you get as reward. At least it's more fun than 'grind 20 of these to get an item/money/achievement you don't really need' type of stuff.
