Voyageur

Voyageur is a Unity-based game (I think) with amazing sound and pleasing background visuals.

It's similar to 80 Days in that it's a choice-based travel game revolving around buying items at a low price and selling them at a higher price. This mechanic fuels your ability to dive ever deeper to the center of the universe, meeting different planets that are parts of different factions along the way.

This game makes heavy use of procedural generation, sort of a text version of No Man's Sky.

With both No Man's Sky and Voyageur, I felt that maybe that procedural elements were pushed a bit higher than the scripted parts. Many of the planets eventually began blurring together.

I reached an ending that satisfied me. A mellow game, good to play at leisure.
