if you think about getting the PC version of the game update it to 1.02 lot's of bugs are fixed in that patch, and also the trainer's work flawlesly with that update
The game is totally worth buying, not sure about the DLCs, but if you are a fan you will want to have them. I guess you could classify the game as a 3rd person tactical shooter. You shoot weapons around, command some teammates, use various abilities, upgrade weapons and all sorts of different stuff like that.

"Requires" is not the word I would have used, it gives you the option between a savegame from Mass Effect 1 with all your decisions and whatnot on it or a default one, whose decisions are already "made" for you, no need to even play Mass Effect 1.
But yes do get it.
And sorry I didn't realise the user above had bumped this.
