On #14 I had Pillars of Eternity. Some of the same guys made a similar game - 15 years earlier. Baldur's Gate was the first game to use the Infinity engine, and these games including also Planescape Torment and Icewind Dale are often referred to as Infinity games, as they share gameplay, graphics and complexity.
Complexity is the keyword here. Baldur's Gate is a game which often allowed you to play how you want. Decide which party members to recruit. Which way to go. Be evil or a do-gooder. In a way it is a Skyrim with isometric view, a party (instead of a single fighter) and a better battle system.
Interplay projected 200K sales, the game in the end sold past 2 million, a major success for the time.
A few years ago an enhanced version was released, most importantly it updated the resolution. The screenshot above is actually from the enhanced edition.
