Would your LIs from each game get along with each other?

Zevran, Fenris, and Solas... they would be civil and act like adults. Zevran, of course, gets along with anyone. Fenris is deeply traumatized and fears magic, but he can be civil with someone if that person is an accepted member of the group. And while Solas is introverted and not necessarily good at making friends, he'd come around eventually. Or I guess I should say, the others would come around eventually.

So yeah, Fenris and Solas would clash the most, but Solas is patient around people like Fenris.

EDIT: Oh and of course those are just the "main" romances, I guess. My favorite from each game. I've also romanced Isabela, Anders, Merrill, Bull, and Cullen.

They'd probably get along. Although, Cullen and Fenris might think Alistair doesn't take things seriously enough.

I haven't decided who I'm gonna romance in DAI.

As for the DAO/DA2 LIs, I remember that Gaider made sure Morrigan wouldn't get along with a single companion in the game, so I doubt she would be nice to Merrill either.

Zevran, Fenris and Solas.

…I don't know. They're all perfectly capable of being civil to each other. The biggest threat would be Fenris learning a bit too much about Solas and getting his hate on, but Solas isn't that careless. And neither would be very impressed with Zevran's casual advances. I guess they'd just work together to get out of the situation with Zevran doing most of the talking? Aside from being cynical, handsome elves with smoky voices, they don't actually have anything in common. They'd be a badass team if some unfortunate pirates stumbled upon them though.

Alistair, Fenris and Dorian.
I think there is some high potential they all end up silently pissed at each others.
Fenris would be the worst obviously. Dorian would apologize a lot. Then Dorian would get pissed as well. But then they'd bond over their love of murdering magisters and wine.
Alistair at first would win them over...but Dorian and Fenris would end up finding him whiny and childish. Alistair would end up pretty passive agressive with those two.
Lots and lots and lots of eyerolls all around.

Let's see...two former templars (Alistair and Cullen) and a guy who hates/dislikes/fears magic and would likely look up to the templars (Fenris)
I think at first they might be wary around one another
they've met each other before (Cullen knows Fenris from when he traveled with Hawke, and Alistair met both Cullen(during the Blight) and Fenris (during his visit to Kirkwall)
though I actually think they would get along quite well after the first round of awkwardness

I find it difficult to contribute to the poll because it is so much of a case of depends on which combination I chose as I have several to choose from. Of my top 3 combinations:

3 elven romances (Zevran/Fenris/Solas): Depends on which stage they meet. I mean after Trespasser Fenris would attempt to kill Solas and be turned to Stone. Back in DAI timescale I imagine a great deal of bickering between Fenris and Solas in pretty much a re-run of Fenris/Anders. Solas can get pretty heated and snarky if he doesn't approve of you and whilst he would sympathise with Fenris' background influencing his prejudice against mages, I don't think he would allow it to excuse him altogether, so I can imagine a whole string of "Solas Disapproves" every time Fenris opens his mouth. Zevran would probably just sit back and chill, occasionally throwing the odd comment in just to set one of them off but also trying to diffuse the situation with humour. I think he might pick up on Solas' evasive answers to some questions and realise he was hiding something, so he wouldn't trust him. I reckon he'd get on just fine with Fenris though.

3 mage romances (Morrigan/Anders/Solas): This would be an interesting combination. Solas would snark Morrigan a lot if she was pulling her superior knowledge line but they do seem to have a common interest in preserving and restoring the past, so once she realised he was genuinely knowledgeable she might back off a little in the interests of learning something. We never learn his attitude to Kieran so that could be a cause of contention between them (particularly if this is before Flemeth removes the old god soul). Solas would probably get on just fine with Anders/Justice. He would understand what was going on there better than most and he might even approve of his symbolic blowing up of the Chantry in the cause of mage freedom. It depends on whether he thought it galvanised the mages into action or made things worse for them. Morrigan had no respect for Circle mages anyway so I doubt she'd hold it against Anders.

My canon romances: (Zevran/Fenris/Dorian): Zevran and Dorian would probably get on just fine, trading snarky comments and enjoying sending up other people. Zevran might even pass on some interesting sex anecdotes that would amuse Dorian and vice versa. Fenris would probably just tolerate Dorian providing he didn't start on his "slavery is better than the alienage" line. Somehow I don't see that going down too well. There would probably a lot of supressed glowing on Fenris' part.

I've crafted a new world state, with Morrigan/Fenris/Sera.  Fenris and Sera would get along just fine but they'd be hissing at Morrigan like terrified angry cats and she might turn into a dragon and eat them out of spite.

This thread being bumped reminded me that I have a world state where the romances are Morrigan, Merrill and Solas. If feel like that could only end horribly. I guess Solas ultimately wins whatever fight there is, but I do wonder if he could survive being chewed on by a dragon. And Merrill is scrappy.

On the other hand, the world state with Leliana, Merrill and Josephine is a happy place where people politely drink tea and talk about how cute nugs are.

Morrigan and Anders.... aligned in many things but clashing personalities. In the end, they'd get along fine.

Anyone would get along with my DAI romance since anyone can get along with "none"
