Okay spent some more time with the game. A few thoughts (semi-spoiler free):
-The RPG elements are extremely dumbed down. Fewer options for customizing your character, armor, weapons, etc compared to ME1.
-The shooting elements are improved
but at a cost, the "heat clips" take a bit of getting used to, especially if you are used to unlimited ammo from ME1
-The dialog is twice as good, if that's even possible. Shepard is more of a badass. AWESOME.
-The story is (so far) a million times better.
Lots of plot twists and turns.
I'm SO GLAD I tried not to spoil myself.
-Hacking/decryption are better, but still a bit tedious. I'm still on the fence about losing the Mako.
Too bad my sick girlfriend is watching Oprah right now, or I'd be playing more!
