About halfway through my second ME2 playthrough (using my renegade Shepard from ME). Renegade Shepard is just so badass. Gave him reddish eyes and with the scars he looks like the ultimate villain. Looks especially cool in the dark. Playing as a Vanguard too, which is actually more fun than being a soldier. You get all these cool heavy weapons on top of all the powers (charge ftmfw!). Have been using the Singularity Projector a lot more as well.
EDIT: Also, since my renegade Shepard was a level 59 on ME, I started this playthrough with 55000 of each mineral (yup, including Element Zero) and about 350k credits. Have done like zero mining so far.
