How much does your Origin's and Awakening save file matter in DA2?

I have PC, PS3, and 360 and was wondering which version would be the best? I bought Dragon Age origins for 360, but back then I didn't have a PS3 or a PC that could play it.

I'm not overweight.

If I just watched a scary movie or something, then I might leave the TV on. But normally i'm not scared of the dark.

I'm not sure if I will even want kids, there very annoying and hard to take care of. I would rather just have a dog. But if I do have them, then I don't want them until I'm atleast 30.

Probably Mass Effect 2

Get back to working out...i took like a 2-3 month break and it's time i get back into it...
