i play this game in all forms ie on-line , a- spec and arcade mode. every now and then i like to use arcade mode for a quick race. in gt5p you were able to adjust the ai difficulty with a simple slider bar. when i have an arcade race or a race in practice mode i am finding it really easy and have no real competition thus dampening my enjoyment of the game. can we adjust the ai? if not does anyone think they will implement this in the future. this is not meant to be a complaint as i love the game and will continue to play it in all its formats.
