BaseSimpleGame and SimpleGame Comparison

hi… iva got questions… could you tell me the comparison between basesimplegame and simplegame… I've tried both simple game and base game… and I think I got the hang of it for both… anyway, what are the functions used in basesimplegame…? are they somewhat alike? i mean do you get to use rootNode in basesimple or just a node that will get the content pane of the whole scene? thanks in advance for replies…xD

its best if you look at the source

SimpleGame extends BaseSimpleGame. So all the functionality in SimpleGame.
