Only played 4 games in the (almost) week I've had the game.  I like '09 so far- the improvements to the presentation, graphics, accessibility, and gameplay are all immediately noticeable.  Still haven't attempted an online game yet, or even begun franchise, etc.  I'll send along more in depth impressions as I play more, but for now I'll say that Madden 09 is looking like a very good game.
