I will second this - there is no way NFL 2K5 should be easy for a Madden gamer. Madden isn't even real football, it is like playing checkers. NFL 2K5 is an entire different thing, it is chess. Madden is dictated by choppy animations while NFL 2K relys on physics. With perfect sliders, NFL 2K5 is state of the art football game. Why else are people still comparing this old game and not games like GameDay and Fever? Simple. NFL 2K5 is a real football game. You guys have to play more games to understand the controls, it is a different game. Don't expect to pick it up and know how to play. That's like saying... "I am good at Call of Duty, so I can play Batman Arkham Aslyum like nothing" Totally different. Ones a first person shooter, ones an action game. For Madden, it is like half NFL Blitz half Football and 2K is pure simulation.
So I do not know what you find easy about this game - but if its easy, check the difficulty.
