Allow certain opportunities to flirt during dialogues. Maybe not start to finish, but it least early on allow players the ability to have minor flirting that if the player flirts later dialogues provide more flirting options.
My big issue isn't personalities as much as no leading up to sex. It is SO lacking romance. My first playthrough, I was stunned that anyone wanted to have sex with me. There was nothing leading up to it.
Also, don't have characters solicit sex. The player should initiate, and if the right flirting options are chosen it builds up to something more.
When I talked to Wyll and he hit on my main, I was floored. I didn't get a homosexual vibe from him at all during the game. We were more like buds. Im not homosexual, and at was not fun. I can only assume the same if you are the opposite. Let the player lead. That way they can choose who they want. Having EVERYONE want to have sex with you is also not fun or realistic. Astarion, I can understand hitting on everyone and coming right out with it. Lae'zel too. The others. No.
I think it is true that every is assuming a lot about these characters. I think Lae'zel also has something HUGE she is hiding. She's softer than she pretends and me thinks she is a bit TOO zealous. I think she's definitely done something against her people. That's why she's so scared. Shes done something to jeopardize her future with her people. Why was she on the nautiloid as a prisoner? Why does she desperately need your help so much? Remember the first mind touch? A Githyanki silver sword was mentioned, but she's not Kith. Did she steal one, kill a Kith...
Gale is hiding way more. Just look at the art. That scene with him and lightning and undead. He looked insane. I like Gale but his secret told a different side to him...a power hungry obsessive side.
Wyll is also a raging ball of anger under that calm exterior. His secret definitely has hardly had the surface scratched. Same with Astarion and Shadowheart.
Larian has 3 acts to tell their stories. They have to reveal some secrets this early or it'll feel too rushed later. I want more character interaction not less. We need more leading up to romance.
Honestly, though, romance shouldn't even be possible for most until later acts. Astarion, I could see. He's free and looking to experience life again. Everyone else. No. Needs more relationship development first.
As for secrets, I disagree. They aren't really secrets. These are just facts about their lives that over time they are willing to share once trust is built. Gale, for example, keeps warning you right from the beginning not to let him die. Wyll's mind link tells you a bit about his and if he's with you fighting gobbos he says he'll open up later without much effort.
Astarion is definitely a secret and revealed early, but it is because he's having a hard time hiding it. Totally believable to me. Shadowheart requires some high difficulty rolls to get her to open up, so hers is definitely a secret and not really that easy to get her to spill. I think it was 2 difficulty rolls of 15 or higher?
So not really all secrets. They just don't share right away for typical reasons. They're getting to know one another.
But Shadowheart does make it obvious she has a secret and then shuts you down. Maybe her lack of ability to hide it is why her intelligence is so low. Maybe that's why she can't remember anything. Maybe she's actually not trusted with the secrets she knows.
Many scenes are skipped, cuz they are not finalized. Many scenes with Astarion, for example, are pulled out. And in these scenes, MC takes a romantic interest in Astarion. And right now Astarion himself has at least 2 scenes where he shows his interest. In short, I think we should have more cutscenes, Larian just still working on them. It's possible that other companions have more scenes too.
If speaking not about romance, for example, the book scene was only added in patch 4. So I think they will be able to fill in these "gaps".
