I would LOVE to see a PC hockey game but where you could make player attributes and create your own teams, much like PP the possibilities could be endless. I have really wondered about the rights issue (if HB can get around recreations of golf courses- not designed by them- if an end user makes Augusta they have no control- would they have the same argument for Hockey?- users would have to design jerseys etc.. and to be honest the jerseys wouldn't really even bother me if you could get the teams spot on.
Honestly NFL/NCAA football would probably be a bigger draw though and while a distant 2nd in my desires I would definitely pick it up.
