I would love more variety as well In their costumes, not only Oci's, would be cool as well I'm a Siam fan so a fancy Siam would make my day.
But who knows what type of fancy cats we have not found yet

As for the traits: I think it depends on how we look at them.
For a collector only a fancy costume and one passible eye as is now might be enough but I agree also it would be awesome if it would cut both ways for the collector and the breeder and therefore would have the interest of a wider variety of Kitty lovers.
The die hard breeder who cares less for costumes and more for traits as well as collectors and everyone in between.
I myself am not a huge Oci fan, it is one of my least favorite furs, well untill I saw the Oci Blue that one I really love.
Currently I'm collecting gems as well and I can imagine why it would be helpful indeed, to avoid double fancies, if people could have a choice or if the system somehow would register what people already own to avoid double cats.
Because I agree to achieve especially a first fancy kitty is pretty costy.
I think it is hard to compair Le Tigre with the Fancy Cats if only because they developed this gem system and these cats around July 2011 when they just started.
