I love simple gameboard, the rules that don't confusing but fun to play.

here my ideas, i call it "Diamond Rush"

your mission is to collecting diamond and bring it back to your chest, stealing it from your opponent chest, or by knocking them, also you can cutting the tree, use 3 weapon: sword (available at board) dynamite & gun (you must go onto map tile to get this weapon, and roll the dice odd number for gun even number for dynamite)

I made it with nice storage system to store all part, a custom 4x4 tile with grass printing, and a ton of fun when you physically knock down an enemy by gun.

off course this is lego, you can costumize the rules by your own by adding card mission etc.
