Which solo game did you love that you think would be better with 2?

Hello friends,
I know this is the solo group, but i feel this group of gamers is likely better suited to answer this ask. I have a weekly group, but it's often that 2 of the players who have lives can't make it, and two of us, one of which is soft retired(retired but may return to work).

I am ideally looking for a fun/interesting campaign adventure game recommendations.
We are playing Arydia with the larger group and enjoying that. My friend has earthborn rangers but didnt love playing it solo...but that could be an option. I have MD 2 and the campaign, but am likely going to play that with the wife. Otherwise would love to hear some potential recommendations. (we have also been through the 'havens and 7th's neither of which i really would ever recommend to anyone).

TIA and if obviously if this is against the guidelines, i apologize :)
