I was exploring and came across Pocket Planes, which had its servers shut down in 2015. Turns out they relaunched last year, so I’m going to give it a try again.
What else comes to mind?
I occasionally replay Alien Legacy (1994). A flawed, but ambitious game of surprising scope. The original Civilization or Civ2. The original Deus Ex.
More recently? Sunless Sea is usually a fun replay.
