Houses are no longer cleaned or repaired regularly, textures should gradually become dusty, walls should lose their paint, outside should have details of dirt, moss and dark polution marks and inside should have details of seepage and mold with wall debris on the floor, in a Silent Hill 2 or Chernobyl vibe, you know?
I feel this needs to be more aggressive in the game.
It seems that the houses, internally and externally, do not follow the advance of vegetation at the same intensity, after a long time everything is still clean, perfect and happy.
Anything metal in the game should oxidize; cars, grills, garbage cans, blades, poles, even slides, swings, etc. everything should loose paint and rust.
The woods should rot too.
