When it comes to Mass Effect and how shamelessly overt it is as far as 'good choice' vs 'bad choice', I would be ok with it if Bioware had bothered to make it rewarding for players who went with their gut instead of just min/maxing for points.
My Shepherd reacted as I would in the situation he was in - skeptical and aggressive with people he didn't know/trust, totally loyal and supportive to crew mates and friends. I didn't think long and hard over every decision, because the answer always seemed obvious to me.
The problem is, that playstyle FUCKED YOU OVER, because Bioware for some moronic reason decided to tie in-game abilities and conversation choices to playstyles that read like hilarious characters.
I'm not ashamed to say that for my second play-through, I tampered the HELL out of that save-file to ensure that I had EVERY conversation choice available to me. If you want me to role-play, then don't funnel me down your bullshit white-hat, black-hat paths.
