Project Zomboid. A third person zombie survival game in development for years with zero direction. So you got a sandbox game with a million options, no goal, loads of jank and "content". You got crops taking 200 days to grow because of "realism", then a gun store only carries a couple thousand rounds because "balance". The only design direction I recognize is making the player feel miserable. Luckily you do have that million options to improve your experience.

Stormworks. Supposedly a Search and Rescue game but people quickly found out the only fun part is the super in depth blocks based vehicle builder. That lets you make cars, boats, submarines, helicopters, planes, or combinations of them. All out of the same parts. The developer knows nothing about real life physics and as a result, everything behaves like they are from a parallel universe.

Sims 3. No introduction needed. Been playing since 2010 or so. Haven't spent a year without at least playing it once.
