Yeah I agree for all that stuff to come in, my big one is the rolling ball physics of the game. Currently you can have a forward handball into space (especially 15-20m) away from boundary line/ goal line and it just picks up speed and rolls over.
- need the ball to bounce at random angle depending on position of the ball
- Wet - skids on or stops still
- dry - bounces more
I think if that were to come in too it would add a bit more to the game
