Those last ones were just power ups though. It's not like you had to collect every single one in the game. But you make a good point, that's one hell of a lot of extra crap to worry about. Presents, oranges, gold bars, golden crocodiles, acorns, worms... oh smeg I'm about to recant the entire game in a single paragraph :P
Nevertheless every game where the character had either lots of special moves or weapons required you to collect ammo or power sources. What about all the stuff you had to collect in every great FPS you had to play? And hey, this is a Final Fantasy fan community too: Final Fantasy might be the one of the biggest collect-a-thons of them all, what with all those potions, ethers, swords, spells, shields, Materia, helmets, summons, suits of armour, chocobo feed, accessories, money, Magicite, status recovery items, gambits, Key Items, bits of clothing for Cloud to dress in drag, spheres, Blitzball players...
Now that I think about it, I've seen very few games that don't amount to gargantuan collect-a-thons, and most of those were fighting games. Even then, Mortal Kombat managed to achieve that (scowls at Deception's Konquest Mode...)
