Even if there were no associate morale bonuses, I think my "nightmares" and "memory" systems could help make the game seem a bit more alive to, in that you'd have some rare and flavourful stuff happen.
To summarize:
You'll occasionally have a creepy nightmare (described mostly through text, maybe playable though!) and you'll either sleep normally, wake up, or wake up screaming.
Also, sometimes you might see (what you think is) a familiar face in the crowd, and get a brief bit of text about it, or a familiar location "Have I been here before?" "A face in the crowd looks familiar... is that... dad?" "She looks at me with those empty eyes, as if she wanted me to remember... no, it couldn't be. It's not her. That would be crazy..."
I know a lot of people play with schitzo not for the points, but simply because it is entertaining, and I think adding in a lot of little touches like the stuff above would help too.
But additional flourishes for physical locations would be great as well - perhaps "themes" to tie the rooms of houses together the way shelf sections in groceries are tied together? It's already sort of there with "fridge room" and "clothes room" and "bathroom", but if the possessions in a room could be tied to something a bit more specific, it would do a lot to give the houses a sense of personality... more furniture and "flavour" items might help there as well. Posters, chairs (pick-up-able!), tables, couches, chess boards, weight benches (mmm... barbell weapons), sewing machines (more efficient use of sewing kits, but take batteries!), instruments (I know I've suggested guitars), televisions (slow but damaging weapons, electronic parts)...
Actually none of that might even be that difficult. I'm gonna have a look through and see what it would take to mess with that stuff (since I stopped working on my inventory mod a while ago when whales said he was making the changes anyway)
