Well, there are many ideas, I will try to synthesize.
- Companions:
1- IDLE animation - random animations, AI, for example in Stronghold (like tidying up the house, fixing something, etc);
2 - Random conversations (perhaps the one that involves more work by the DEVs), random animations everywhere - something like looking at the hands, moving, itself, etc .;
3 - Open loving relationships (without any kind of restriction or preconception) such as hugging your partner, kissing, etc., respecting the rules of the game / EA game; Random missions on planets to gain sympathy, affection, awards that release animations, for example (in order to embrace, you have to have 'x points', to kiss, 'y points', to make your partner do such a task, 'z points' ).
4 - Customization of bodies (companions);
5 - More outfits options for all, players and companions;
Well, the secret of a good game is his ability to 'hold people' in the immersion. I think Swtor is undoubtedly one of the few games that explores this well.
