While a nice idea, I think B&W 1 modding was pushed about as far as it could.
There just isn't any will left to do much with it. If you've got Creature Isle, you can try the Black & White Eruption mod. While not as ambitious in scope as OGAM is for B&W 2, it's still quite good and the most substantial mod written (if I'm not mistaken) for B&W1.
