Well I am on my second playthrough and I have both my renegade and paragon achievements now. Its harder for me to play Renegade. To be honest, I am not a real renegade. I accomplished the same things for the most part I just wasn't nice about it. Somethings I just couldn't make myself do.
SPOILER:
On Noveria you can hack the door to get to Benezia, doing so makes all of the guards aggro to you and you can kill them all. I couldn't do that, so I did the side mission for the cure for the sick patients and got the doctors pass. I coudn't kill the Rachni Queen either. I mean you are on a mission to stop Saren from bring about the genocide of all advanced organic life, it would be hypocritical to do the same to the Rachni.
SPOILER over:
Yeah I really wanted to learn more about Tali as well. I did help her with her pilgrimage but I wanted to actually see what a Quarian looks like out side of the protective mask. If I had my choice, I would have hooked up with Tali, I liked her voice and her intelligence. I ended up picking Ashley on my first play through. It was fun finding out about her past and getting her to stop being so xenophobic about aliens.
SPOILER:
You can actually drag out your choice between Liara and Ashley. If you can tell them both you have have feelings for them. They will both confront you eventually. Thats the route I took in the game. I was trying to get both of them ala Jade Empire plus I was unsure of who I wanted to pick. I thought it was funny to see Ashley fighting over Shepard. Liara is so diplomatic about things but Ashley was pissed off.
SPOILER over:
Bah, I have to get back to work. I can talk about Mass Effect all day.
