There are two reasons Dishonored 2 ($40 on Humble) could make this list. One is rather ignominious: It may quite literally punish your PC. On release, Dishonored 2 was knocked for being poorly optimized, with the game suffering from all manner of stuttering and bugs. Those issues are mostly rectified, though you’ll still see scattered claims on Steam of poor performance—and the game can indeed be a bear if you try to run it maxed out.
Set aside the lackluster initial PC port, though, and Dishonored 2 is quite an impressive piece of work. Its missions attempt feats I’ve never seen before in any game, such as the Clockwork Mansion, a house that rearranges itself as you traverse through it, whole walls sliding into the floor and new passages appearing at the pull of a lever. The writing ain’t any better than in the first Dishonored (and in some cases it’s worse), but the level design at least makes Deus Ex: Mankind Divided look archaic by comparison.
Arkane also released Prey ($40 on HumbleRemove product link) in 2017. It’s worth noting because the port runs (on average) quite a bit better than Dishonored 2 and looks just as visually stunning. If you prefer System Shock 2 to Thief, space vistas to pseudo-Victorian “whalepunk,” then be sure to check out Prey ($40 on Humble). It’s fantastic—probably one of 2017’s top games.
