That's a fine reply from EA... but if Fox bothers to mention the matter again (which is questionable), it's likely they'll just talk about getting 'hate mail' from EA, followed with some highly selective quote mining of the letter itself:
Love scenes... include side and profile shots - a vantage frequently used in... television shows. Sex scenes in Mass Effect are... very similar to sex sequences frequently seen in prime time.

Mass Effect and all related marketing has been reviewed by the Entertainment Software Rating Board (ESRB) and rated... appropriate for players.

As video games continue to take audiences away from television, we expect to see more TV news stories warning parents about the corrupting influence of interactive entertainment.. a new level of recklessness.

Do you watch the Fox Network? Do you watch Family Guy? Have you ever seen The OC? ...the sexual situations in Mass Effect are... more graphic than scenes routinely aired...

...young people have more exposure to Mass Effect than to those prime time shows...

...a legal threat... to... FNC
