What really makes these kinds of games great are awesome breeding systems. I absolutely LOVE how you combine monsters in Jade Cocoon and the resulting monster will retain not only combat attributes of both parents, but would also would visually be a cross. Like if you combined a cat monster with a bird you might get a cat with wings or some crap. DWM / Joker's breeding systems are a ton of fun too. That's one thing I've felt Pokemon is missing somehow, it's breeding system doesn't speak to me at all.
Have you played Monster Rancher? The breeding system is pretty similar to that.
