Gomo: Ok puzzle adventure game, with only occasional need to notice the necessary detail as a blocker making it difficult.
The Gunk: 3d puzzle platformer - overall pretty good, but not so mad about the character interaction or the pace of gunk removal (a little frustrating even after upgrading)
9 Clues 2: Enjoyed this well-implemented HOG, but it was very gentle on standard difficulty (and I did a quick run on easy afterwards to pick up the remaining achievements) - there appears to be no driver to do it on Advanced difficulty other than the satisfaction of having done so.
Red Dead Redemption II: Far more enjoyable than I was expecting. I played RDR Online a while back (the achievements ported over to RDR2), and found it very sterile, and have never particularly enjoyed the quests in the GTAs. The single player on this game had a fairly vibrant world, mostly non-annoying quests, and lots of short contextual conversations available. Actual gunfighting was relatively easy with autotargetting, and the ability to skip on failure during missions was a reassurance (though never used). Lots of game still available if I feel like getting completionist (but I probably won’t – HLTB is saying another ~130 hours for a complete run!)
