Btw, I checked out the graphics of the old games and thought "Maybe nice, but probably too old to play these days".
You don't play the 1st one for the graphics, but for the story that will keep you interested in the game and up all night. As far as 2D graphics go, that game outshines other 2D games I've played. Since Divinity 1, it has become hard for me to get into another PC game. They are mostly hack and slash and no real story or interesting NPCs.
EDIT:
And btw, the Achievments were because of the X-box version. A bunch of people are hoping Larian releases a patch to remove them from the PC version.
