To me, both Outer Wilds and The Witness were absolutlely savourable, and I made a point of never looking up anything on the Internet while playing these games. That would rob me of the feelings these games were designed to impart.
Tunic is so good. Although I'm yet to complete it, I've gotten like 90% of the way I think after runs of 20-50%. Maybe I'll finally complete it this year because I adore the aesthetic, vibe and that little fox.
Definitely the game opens up and becomes more deep/mysterious than I thought it would get, super cool.
