I love looting and mining but spend most of my time building new ways to kill zeds. I've built mazes, dead drops, collapsing ceilings etc. The ceilings are fun if you can get the zeds to Target the right pillars.
On PS4 the best part is playing with a friend on split screen to see what you can come up with building wise but the pov is murder. The bugs get me hardest though and usually necessitate stepping away for awhile.
My favorite though is playing Navezgane in single shots. Start with walking dead style no runners but dying once means you have to quit. It's interesting to see how far you can get and build your own lore. Or role play that if you dieyour next spawn is just a random dude who stumbled across this dead guys base kind of thing.
