Lets be honest it's a bit of a shambles but someone at BA must have a metric that suggests it's a positive move, they're far from daft. It's a difficult one for Big Ant, balancing showing off the nuances of the game (in what is a very nuanced sport) which are probably more readily viewable a on harder mode vs the skill/interest of the IGN person sent along to play it. Whilst also factoring in that the target audience for this video is most likely to be people significantly younger than, say, me!
I get the feeling that this is probably going to be like 2 games in 1. Proper pick up and play, hit and giggle stuff in easy mode then hopefully a more hardcore experience on the higher difficulty settings. IF that is the case BA are onto a winner.
