Mine are 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’m sorry for my bad English ^^')
I really love point and click adventures. Especially those like the old ones from LucasArts. No rush, no quick reflexes, just your brain and a fun time.
