Some possible advantages for Predator over Stern pros, hand drawn art, possibly a better speaker system, custom toys, and according to Kevin unless there are bugs finished code.
I do like the green pop bumper covers, but might have liked a brown color better to make them look like jungle huts. I think red pop bumper covers would make too much red on the game, and does not fit with the jungle art. The hanging body probably needs some artificial foliage added to make it look more like it is hanging from a tree.
