I finished it (took longer to download than play) and loved it. Any spoilers are speculations that the 2nd mission make me think of, and I have a lot of them. I don’t consider anything from the first mission to be a spoiler, as it’s the first mission. I played it first, so consider it part of the game.
On to the specifics:
Gawd the world is beautiful. Look at that water!
It seemed hard to control, compared to ME2. My character was too much in the way and things were too hard to find. Though, I had this problem with ME2 after playing ME1, and they went away so I’m willing to guess that they’ll do so here as well.
Love the new leveling system. You at least get 2 points per level up through the first 24 or 25 levels (I levelled up mid-game and think I still got 2 points, and started at level 24). I didn’t notice how many points my cronies had, but when I levelled up they only got one each.
Each tree took 6+5+4+3+2+1=18 points to level up. There were 6 (7?) trees so you’d need 6*18=108 points total. That implies that, to max out, you’d stop getting 2 points per level at around level 48 or so. Any less and you can’t max out.
Spoilers from the DEMO. If you’ve played the demo, you can read these:
[spoiler]
Wrex! Ashley! (And I’d assume Kaiden!)
Seems like Ashley or Kaiden will be teammates. Wrex will probably not. Ashley got a major rework and looks even more beautiful than before.
You start on Earth, not part of the military but not part of Cerberus. I wonder what’s up with that?
Why are you freeing Krogan females (other than it’s the right thing to do)? My guess is that the Krogan (through Wrex) are needed to fight the Reapers and they refuse until they get a bona-fide cure for the genophage.
