How much needs to be played of the Kingdom of Almur demo to get the ME3 content? Something unlocked after I made it out of the tutorial area, but I cant remember what I unlocked. I didn't like the game enough to warrant the rest of the 45 minute demo, but if I have to, I will go back and do what needs to be done.

Im pretty sure you just need to start it, play it for a sec, then close it and you got it.

Edit: I was wrong.

I got the ME3 unlocks right at the start.

You get something when you finish the demo as well, I don't remember if it's for Amalur or ME3, though. 
 
Edit: Looks like you have to play through the whole demo to get all the ME3 items (a gun for finishing it, at least that's what Google says).

Thanks! Unless anyone can confirm what else is unlocked at the end of the demo, I guess Ill just have to find some time and get through it.

armor on start up and gun is on finishing the 45 min demo just let it run and do laundry or something

You get the chakram launcher for completing the demo. You need to get out of the tutorial area and talk to the fateweaver guy, then a message will pop up saying you have 45 minutes to play. Just leave the game running, not paused or anything, and wait for time to run out.
