NO, they should compare BOTH games to real NFL football.
THAT'S the standard. THAT'S why we play... So we arm-chair quaterback/weekend warrior types can get the closest feel possible to being in the NFL.
To do anything besides this is a complete biased travesty.
All games that CLAIM TO BE SIMULATIONS, (thus Blitz, NBA street, etc. are exluded) need to be compared to the REAL NFL. HOW WELL DOES THIS GAME MAKE A PLAYER FEEL LIKE HE'S IN THE REAL NFL.
