Mweor is a breeding/roleplay sim based around creatures called Mweors, which are all very much similar to cats.
The mweor above is a Longhair mweor, one of several breeds that can be bought, bred, or even custom-made if you buy a statue with MP(Mweor Points, the premium currency).
The game itself has a nice breeding setup, with some simple genetics coming into play. The community is a little bit clique-ish, but the game itself is a lot of fun.
Does anyone else play?
