The only thing I can point out in a devil's advocate way here is this:

Most games in a fantasy setting do have the 'find this monster, kill it, and bring me stuff'. I'm not just talking about WoW here, but even DnD. I mean, what is a dungeon crawl besides an intrusion into an environment free of man, killing everything inside, and taking the choice bits home? Sure, the dragon is 'evil', but you're still going in there to fuck up his shit and later take his blood to an alchemist for eleventy billion gold.

Monster Hunter basically is a hyper-streamlined version of this. Find a monster, kill it, take its stuff, repeat.

Someone else mentioned Shadow of the Collosus elsewhere on this thread and it's an awesome treatment of ye olde treasure hunter meme. You go around killing these amazing and inspiring monsters because some shadowy dude made a deal to bring back a dead chick for you.

In the end it's revealed what a stupendous fuck up this is, and the girl is more offended that you killed the gaurdians than she is happy you brought her back.

It makes you feel fucking awful and question the sort of 'kill quests' you get in just about every fantasy game ever.
