Trauma is definitely such a game dealing with pretty ordinary human issues, even if it uses a dream world made of broken memories for the player to explore.

I think Return to Mysterious Island was also pretty well grounded in reality - your primary goal was survival. Exploring the environment and making use of it. Well, the game is like that for a while, but later on the Captain Nemo subplot significantly changes (expands?) the tone.
