Mine is vehicle building games like Stormworks or Scrap Mechanic. It’s so much fun to shoot at your friends with your latest nuclear drone while hiding in your bunker with a better defence system than Area 51 !
I’m very curious about your fav niche game genre !

I still remember spending an unhealthy amount of time playing the NES version as a kid. Then traded it for another addiction when I started Civ on PC.
