As the title states it is a great game - interesting story, lots of different choices to make. Unfortunately there are also a lot of oversights and at least one massive game breaking bug. Oversights such as save points not being highlighted everywhere is something you can live with - however there is a bug that is kept throughout the game at the second town which means at some point you won´t be able to progress - simply because you can´t exit the area. So until this is fixed I would not suggest people buying the gog version of the game.
Just having finished the game on second hardest difficulty all I can say that it is a well made game that brings memories back to when I initially played Baldur´s Gate. The story is all in all great, since there is basicly allways something pushing you forward. There is also a wide variety of spells at your disposal, so if one doesn´t work you can get another to do the same thing or gear to do the same. The game isn´t without its flaws though. - Experienced one bug where I couldn´t recieve a side quest which apparently had been in the game a while. - Limited gear selection, or redundant gear. Playing it on the second hardest difficulty I went through most of the game with basic gear without any major issues besides being killed a bit in the beginning. Not to mention it is very few of the factions that are actually needed to get proper upgrades. So gear could have been better implemented. - Ending feels a bit rushed perhaps. I recieved a lot of items during the end part that just took up space. While this might seem more than a few flaws they are also so minor that it isn´t something that removes from the overall experience of the game.
