It is really hard to not recommend this, as I would count Baldur's Gate as my favorite game of all time. So while I am not recommending you buy Baldur's Gate Enhanced Edition, I am still wholeheartedly recommending you get Baldur's Gate, as it is absolutely incredible. If you have never played Baldur's Gate, go to GoG or somewhere and buy the original game. I have easily sunk 200 hours into the original game, back when it required swapping multiple CDs. Only buy this if it is a last resort and you absolutely cannot play Baldur's Gate any other way, as even here it is incredible. But buy the original elsewhere, and not this.
There is really so little work they needed to do to this to make it great. If it was absolutely unchanged it would still be incredible, but sadly the changes they've made are for the worse. There are still stability issues which I don't get with the GoG version, but the most notable problem is the cinematics.
In the original Baldur's Gate, you would get these beautiful (for the time) cut scenes of the area you were entering. The opening cinematic has been replaced with a far worse attempt to recreate it, and most areas have nothing more than a brief glance at the area. The cinematics created such a great feeling of the area you were aout to enter, in nashkel, beregost and the gnoll stronghold, that removing them seriously dents the game experience.
The game of Baldur's Gate itself is as glorious as ever, but this is simply not the best way to play it. It isn't the revamped experience that was promised. It is apparantly possible, with some modding, to get the game back to normal, cinmatics and all, but it seems very backwards to have to do that just to undo the changes that are the supposed selling points of this 'enhanced' game.
