Exploration lovers should not be afraid,ME2 has like 10x ME1 exploration,only difference is that instead of barren wastelands you will be exploring beautiful alien locations,full of life.
Finished the game,Bioware bitchslaped rest of the dev pack,both artistically and technically.Technically the game is so good that it is hard to believe that Bioware made it.
Despite my hate towards EA,i have to say

EA

,they did an amazing technical job,Bioware would never do that alone without EA help.
For those that have beat it, how was the veteran difficulty? I'm thinking about doing that on my first play through.
Play it on Veteran,don't bother with normal.There are two difficulty levels above it,hardcore and insanity.
