It's quite natural to get burnt out on the game...I know back when I bought it every year for the PS2, I'd play pretty much through the actual NFL season, then get bored with it and wait until next year.
This was my first time playing Madden any reasonable amount of time since 07 or so, and I had a lot of fun in the league. I'm not sure if I'll be a day 1 purchase for Madden 12, but a big key to that will be how a league on this site shapes up. I can definitely say that I won't be trying to do two leagues again--it was a good idea at the time and it gave me a taste of the playoffs, but after the first season it just became a grind keeping up with two teams (even one!).
I'll keep up with the thread and I'm open to some random scrims here and there, maybe, although I've been working through my PS3 backlog as of late, the only thing the X360 gets used for these days is You Don't Know Jack with the family. Hope to see you all next year.
IF this league grinds out season 4, and you're playing the Vikes, you can still contact me and I'll attempt to get the game in. I haven't been paying a lot of attention to the schedules but I've played people when they contact me.
