i personally got it a week ago and am loving it. Having had almost all of them since the series first started, i must say this is the best yet, the graphics are improved pretty well on 2003 although its not huge differances the field and players are looking and moving so much more realistically, the select your fav team pref from begining is pretty cool, and i am loving the new playmaker control, its pretty difficult to get used to when throwing but is still good fun. obviously i took the broncos option for my team, and well the playbook and players are almost dead on. although i did take a 5 min quarter against amsterdam, and well destroyed them 113(or close to that) to 21, and the 21 was pure luck by two run backs from kickoff and a lucky break:)
this game is great

well worth getting if your a fan and prob worth the rental if your not
