No idea, but I know a disturbing number of people who, for some reason that is way beyond me, treated the Mass Effect games like shooter games and were disappointed that they had to deal with all the boring stuff...
And I know people who want to experience Mass Effect but can't shoot for ****.
Nowadays you can't just say "deal with it" or "maybe this game just isn't for you" though, you have to make it accessible to everyone.
As much as the mere existence these ridiculous modes amuses me I have to say I'd rather have those than have the game tailored to the lowest common denominator, like they tried, to a degree, with Mass Effect 2, I assume.
