Given that we're talking about this on a porn game thread, I'll add that Isabelle from DA2 is IMO the hottest character in video game history, relative to the game's era. Those thighs!Oh and now that I remember there is another spicy scene.
If you romanced Leliana and had Zevran in your party during the Fade visit in Redcliff you could have foursome with a Desire demon.
When she bargains with you for her life you can choose something like "Pleasures beyond this world" and then you can ask Leliana to go with you and Zevran makes a joke or something and you can bring him as well. Really hot and funny banter.
Hilariously enough if you romance Morrigan bring to the Fade AND accept the demons proposal she´ll get upset and you´ll get minus points with her.
Another threesome / foursome happens with the same people in your party and Isabella the pirate.
She is romancable DAII and is and absolute turbo slut. I think she keeps sleeping around even if you romance her and stops only when it gets serious between her and Hawke.
But my memory on how these scenes exactly play out is hazy since I played the game like 14 years ago. I´m slowly going through BG3 and holy shit its the real Dragon Age successor. Far more than whatever the fuck DAII was. Inquisition is OK though.
I thought Alistair was an ok character in my playthrough. He started as a sheltered sensitive bitch-boy and by the end of my game was a gigachad king.
Oh and the banter he has with Morrigan while traveling is prime comedy gold. It depends how you influence and interact with him. Its better to have patience while playing these long narative games than to throw a temper tantrum over a character that has yet to go through any development.
It was a damn shame that Bioware changed their character models after that.
