Already? I was a first day buyer and I think it's normal (I've played it for 90 hours already), not to mention that a prospective buyer will probably get Karkand as well.
Considering you could get it for free from day 1 many of the players likely got it when they upgraded their GPU for it...
If I would buy first 2 mass effects in steam at some point of my crappy life. You can import that character in in ME3 right?
..and yes, questions without answers.. awesome.
Yes you can import them, you'll also find ME2 waiting for you in your origin account and can add ME1 to it using the CD key and the website redemption tool (giving you access to cloud saving for all 3)
My pc tilted and next time it asked would i like to use cloud saves or local.. of course local, were most current. "we are out of sync" (my words) said cloud and not that final fantasy spike hair. I didn't even know that origin had some cloud. I loaded origin because of that demo and tried it and it's weird, even though I own the game, the demo is there but it's... Well I guess some serial thing. I uninstalled it and all.
also.. when I bought in some sale mirrors edge, I didn't get any key.. Well, it works fine, mostly. but still weird game and a bit odd game. but mostly played fear 2 and I started ME3.. they have some similarities but not many. =P
