In Games

So what are some good games that came out for the Famicom but not released in the US?

I only have three famicom carts right now and am looking to expand, but I generally am looking for games I couldn't get for the US NES.

I have rockman4,binaryland, and splatterhouse (wanapaku graffiti, or something).

I was looking around on japangamestock.com, but the only way i could figure a game was noteworhty is if it were expensive.

Any insight would be much appreciated. Thanks.
