Same thing happen to me at my job at Best Buy. I had this vender come in talking about how great Madden was and that he played in tournies. I told him that 2k5 blows away Madden in everthing. I told him pick up 2k5 for like five bucks, he was like cool. I told him just wait until summer and you will be blown away again!
On a side note, for the first time I tried out Madden in like 3 years on my 360 and I must say.... how the hell do you run!? I get stuck on all the players! there is no running game! I am so used to 2k and how you have to fight for yards. And my goodness, the presentation is very bad... there is a freakin pause screen for the halftime show!!!!!
