In a pokemon game or typical single player animal breeding sim, one of the player's major goals is typically to acquire or produce one of every type of pet monster. I love this type of play. But in an MMO environment it would be demotivational to hunters and breeders if every possible type of pet could be bought cheaply. So I was thinking about ways to allow pets to be sold without devaluing them. First thing is simple - make the 'scorebook' of pet capturing only count pets you capture yourself, not purchased ones. Breeding is trickier, because buying two of a pet type and breeding them to produce one of your own would be way too easy, basically cheating. So I was thinking, what if all pets which are traded are automatically neutered? So anyone can sell their captured or bred pets, and these would be bought by people who wanted the pet's looks or functionality but didn't want to do capturing/breeding gameplay. But supplies of pets which required higher levels of capturing and multiple generations of breeding would be in limited supply so they would be a bit more valuable. Also, capturing or breeding all pets of a 'set' would give a set completion bonus, basically a quest reward. Opinions? The alternative would be that pets cannot be sold at all, instead only the resources produced by harvesting pets could be sold (such as wool, horns, scales, and clothing crafted out of them). The disadvantage of this is that players who don't like doing capturing/breeding would have severe limitations on what pets they could obtain (NPC-sold ones or ones given as quest rewards, or the lowest level of easily capturable ones.)
