Romances

In all three Baldur's Gate games, it is possible for your character to enter into a romance with one of your companions, subject to meeting the relevant gender and race criteria (most romanceable companions are heterosexual, and most have restrictions on which races they will romance).

Whilst initially you can start romances with multiple companions, eventually you will forced to decide between them, though you can usually retain the rejected companion in your party with no penalties.

Some romance dialogues will only occur under certain conditions, for example when resting outside or entering a tavern. If it's been a long time since the last dialogue, try resting outside. Romances are usually on hold when you're in a dungeon, so don't expect any dialogues until you emerge. Also, romance timers are generally based on real time, not game time, so travelling long distances or resting will not usually accelerate the process. In Siege of Dragonspear, every 'love talk' (as individual romance dialogues are called) only occurs at certain points in the game, so there is no way to accelerate the process.

It's also possible to 'break off' a romance if you choose the 'wrong' dialogue option. Usually this is obvious - don't say you don't have time to talk when the other character initiates dialogue and generally say nice things about them - but in one or two cases it's possible to end a romance despite saying what you might think is the 'right' thing.

Mods: Installing modifications expands the number of available romances, for example you have the option to romance Imoen. There are mods which allow you to pursue multiple romances to their conclusion.

Baldur's Gate 1

The only romanceable companions in BG1 are the ones added by the Enhanced Edition, i.e. Rasaad, Neera and Dorn. The romances are fairly short - it's possible to finish Neera's before the end of chapter 3 for example - so don't be surprised if you get as far as a quick kiss and then hear nothing else for the rest of the game.

Siege of Dragonspear

Although the shortest game, there are still a number of romances available. Romanceable companions are Safana (m), Viconia (m), Dorn (m/f), Neera (m), Corwin (m/f), Voghiln (f), Glint (m) and Rasaad (f).

Baldur's Gate 2

The second game allows longer and more in-depth romances which can lead to rewarding endings.

Although Shadow's of Arm and Throne of Bhaal are linked, they are treated as separate games for the purposes of romances. As a result, it's possible to reach the end point of a romance in SoA well before the end of the game, and there will be no further interactions until ToB. However, when you proceed to ToB the romance will continue where it left off and there will be additional dialogue options and, if you choose the right options, a final resolution to the romance.
