That's the biggest compliment I can give them, that after watching them play M15, I actually want to play it too. I haven't been able to say that about Madden for awhile, watching people play the last few versions has made me sick to my stomach at times, lol.
Even though I'm buying to support the cause, I hope that desire to play the game extends past the first 2 weeks. Like others have said, I think however CFM turns out will have a huge impact on the longevity of the game for me because regardless how balanced the game is, I can only play so many hollow Online Ranked games.
