I've been looking at 2D side scrollers like "GRIS." If you haven't played Hollow Knight before, I highly recommend it. Retails for $15, but 50+ hours of gameplay. If you have any 2D side scrolling Indie games you can recommend, I'm all ears.
I'm kind of surprised, because I almost never get games during Steam sales, I just don't have much interest. However, I pre-ordered Death Stranding, and Horizon: Zero Dawn. I also just bought FFXV, NBA2K20 (for $11.99 Deluxe Version, the regular version is $8.99), RBI Baseball, and Assetto Corsa Competizione.
Death Stranding and Horizon Zero Dawn I will definitely be picking up later. Right now I'm working on Fire Emblem Three Houses, and I have to play Last of Us Part II and Final Fantasy 7 Remake for the PS4 afterwards lol.
