Speaking for myself, the answer would be "Yes". I had NFL 2K1, 2K2, 2k4 and 2K5, so I am a 2K fan. I was very excited when the game was announced back in January, and followed along closesly as details emerged. It was a bummer when we found out we couldn't recreate the NFL, but I was still onboard...infact I was still intrigued by the fantasy teams. But my interest really faded when I learned how thin the the offline season was. I couldn't modify other teams, limited presentation and it sounded like the same CPU team ("Legends" I think) always made it to the championship.
That was alot of rambling. I think the bottom line is that this game is designed for online play...and I mainly play offline.
