The stat system is unecessary, it's simplicity and implementation create a scenario where ppl will focus on "playing the system"(min-maxing) so they can have access to said choices, as opposed to making the decisions they feel are best for a situation. She should have just opted for a more organic choice system. stat systems like theses don't work well unless their complex and the game is designed around them(a. la Fallout, Arcanum, etc.), hell i'm even playing Dragon Age Origins right now, and their whole "friendship" system make me focus less on dialogue options i feel are best, and more on what "pleases" the character more(I decided to say fuck it, and just Role Play, ignoring the "stat system").
