This is one of the most meditative games I've ever played.
Solve (and create) problems, take things at a relaxed pace by yourself or invite friends over to help things along.
Would've preferred to nominate this game for the Steam 2020 GOTY + Labour of Love + Best Soundtrack + Sit Back and Relax awards, but given that relaxation is what I get most out of Satisfactory, "Sit Back and Relax" is the most appropriate single choice I can go for.
