I'll use those terms lightly since your "Alignment" is decided through conversations. Basically, I'm just wondering if you prefer to be nice to people, or be a complete a-hole, or a little bit of both? --- "Why would hit a poor innocent switch? You monster!" - KeybladeRYNO666
Sometimes the paragon options are better, and sometimes the renegade options are better. Case in point, I like being nice to Conrad Verner until my third encounter with him, then I shove a gun in his face. Nothing beats seeing a grown man cry. --- This is my impaling wall. It's where I put the bodies.
I use a mix of Paragon and Renegade. Not only does it help flesh out your Shepard, but it can end hilariously. My current Shepard is highly cynical and joking, thus I'll always pick some joking response when possible.
Also, TC, I was just thinking how much you reminded me of Santa Clause. --- I don't think a Geth sniper is going to be "Oh I love your hair, it's too nice to mess up by putting a bullet through your skull."- ThaBenMan
In games like this (ie: Kotor, Fallout3, Morrowind) with "good" and "evil" choices I always first play as a totally good guy, then a totally bad guy, to see the two extremes the game offers. then with my third character I either choose a neutral or mixed play through, depend on what I feel like doing at the time. --- http://www.escapistmagazine.com/videos/view/zero-punctuation/2-Psychonauts
