Great PC games on that list now ported to PS4:
Shadow Tactics: Blades of the Shogun (PC release 2016, Metascore 85)
Thimbleweed Park (PC release 2017, Meta 84)
Pillars of Eternity (PC release 2015, Meta 89)
Cities Skylines (PC release 2015, Meta 85)
Undertale (PC release 2015, Meta 92)
Plus, for Myst fans:
Obduction (PC release 2016, Meta 76)
Out of those I've played Pillars, Cities, Thimbleweed and Undertale and loved them all.
Owners of the PC versions acc. to Steamspy: Pillars 980.000, Cities 3.7 million, Undertale 2.7 million.
Thimbleweed Park and Obduction belong to a once popular PC genre only some 10.000 people care about these days. Both will sell not much more than 100.000 copies on PC, but TP creator Ron "Monkey Island" Gilbert can be happy anyway (although he calls himself crumpygamer on Twitter). I did expect Obduction to sell much better on PC though, it's made by Cyan after all, creators of multi-million seller Myst.
Shadow Tactics seems to be the overlooked PC gem here, "only" 150.000 PC players own it acc. to Steamspy despite very good reviews. I ignored it too, I think it's time for me to get the PC version.
