Hi there. is there some game for pc like jade cocoon? something with mixing animals or something and then fighting with them. i played Jade Cocoon on ps1 and that is the best game for ps1 and now i want something like that for PC.

Well the only one I know of is the Shin Megami Tensei series. (I think some games are available for the PC as well.)
You fuse monsters together to create new ones, and they transfer over some of their abilities and such.

*Edit*
There seems to be only one available for PC, and it's an online game.

You'll see monster fusion in that clip.

thanks man. i'll try that. if you find out some other, let me know

Just grind through the Eternal Corridor until it freezes. Years of annoyance/fun.

Give the Monster Rancher a shot. It doesn't really focus on fusing creatures as much as Jade Cocoon does, but you do raise and battle monsters, and whenever you feel it's time to do so, you can fuse them to make something new.

The main attraction, though, is experimenting with all sorts of CD's/DVD's to see what kinds of monsters you can get from them. ^^
