The bowling, in my opinion, needs major tweaking if it is going to possible to get enjoyment out of it. I've just played a game as an experiment, every single ball in the light green zone outside of off stump, hitting the perfect matching colour each time, and mixing up deliveries.
The results were, put simply, perfect Test batting by the AI. Katich took 25 balls to get off the mark, Hughes was restrained and played each ball on its merits. The major flaw with the system is therefore exposed - the AI appear programmed to react to the colour system itself, rather than taking into account length, swing, pace etc. Hit light green and light green, they defend. Hit dark green and dark green, you get smashed. In principle, it sounds like a good idea.
The major problem is that the light green area is a) too small, and b) in the wrong place entirely. The system needs serious work, the game punishes variation and instead encourages monotonous bowling in the same small area outside off stump. Therefore, you are basically unable to get LBW decisions, or clean bowled strikes. The only way in which a batsmen appears to be able to get bowled is to chop onto his own stumps.
I've attached the pics of the test match, along with the pitch maps of Anderson and Broad. You can see where a slight miss of the right area is punished by a rare green dot, indicating a boundary.
