I loved the original Mass Effect. I've played through it multiple times: I have one character at level 60 (canonical, with which I played through thrice), another at level 50-something (female engineer, with which I played through twice), and another at level 40-something (biotic, with which I played through once).
I've recently ordered Mass Effect 2 on Amazon (for GBP 13, what a deal). My question is, should I start Mass Effect 2 continuing one of my Mass Effect playthroughs or "start afresh"? Do you lose much if you start afresh? What do you gain otherwise? What are your experiences either way? Part of me would like to remain canonical with the series, and continue as BioWare suggests the story goes, but I've heard it's a lame choice.
With my level 60 character, I played through the game three times. Each time I did things differently; on the second playthrough I completed each and every quest, even. Now I can't remember what choices I made. On one playthrough, I even killed Wrex, just for the hell of it. Can I start from any of these characters' playthroughs or just the most recent one (the one at level 60 or the one at level 50, for example)? Can I change any of my choices (I seem to have read that I can't, if that's so, bad show, BioWare).
I'm not really invested in any of my characters; but there are some choices I'd prefer rather than others. (Just for the sake of completeness, the major ones: Ashley and Wrex still alive, the council dead, Anderson the human ambassador, all the characters with their subquests completed, Rachni queen alive...)
Are there any choices which have a big impact in the game, or am I just worrying too much about this?
