I realize now just how few games from this year I've actually played.  I've been happy enough to wait for Steam releases of some new release games so there's a few I want to play that I won't until next year.

So my short list would look like:

Ion Fury 
Resident Evil 2
Rage 2
Astral Chain
Link's Awakening

In no particular order except for Ion Fury, which tops out as my favourite.  Though, those are all the 2019 games I've played that I recall, and I enjoyed them all to varying extents.  Two of them are remakes of games from the 90's and one of them is a deliberately retro, throwback shooter.
