>knowing what you're talking about and being passionate about your profession is a bad thing.
Miyamoto's a fucking hack. Everybody knows it, nobody wants to say it to his hack face and fire him.
I see where you're coming from but it's important to be introspective and know the why behind the what. "Why is there ammo? So we can limit the effectiveness of the weapon, or encourage the player to change weapons often and/or aim precisely, and punish the player for wasting it."
The second one is ridiculous though, at best it could mean "Why are there multiple weapons?" but the answer is much more obvious than the previous question.
