Solasta's teammates banter but their relationships don't grow in any meaningful way. I still head-cannon the cleric and ranger having a thing (because of how they tend to finish each-other's ideas) and the sorcerer is really sleazy whenever the ranger crawls ahead... he always says smth like: "You look like you've been doing this all your life" "Spent a lot of time on your knees?" Victor, please, for the love Maraike, shut up!.
This part is funny to me, because one of the remarkable facts about the Solasta dialogue system is that none of these characters you are mentioning "exists" strictly speaking. The whole thing isn't "scripted", but uses a tag-based system where every single member of your party is defined by their tags (background, class, attitude, virtues and flaws, etc) and voice you choose for it.
The fact that you are talking about them as if they had pre-scripted dialogues or predefined personalities just goes to show what a good job they did for this system to create the illusion (even if the voice acting is... Uneven in a best day).
That aside, a fairly good analysis/comparison. I agree with most of it.
