Saving this post because it’s right up my alley so now I have many new games to check out. Project Zomboid is still going strong for us, but here are some others that our group has enjoyed:
Heave Ho: super crude 2D graphics, but absolutely hilarious gameplay
The Ascent: beautiful cyberpunk-themed isometric shooter
Broforce: very entertaining pixel-art 2D platformer/shooter - we played this through to the end, which is rare for us
Overcooked: very entertaining 3D game, not sure what I would even call the genre - a “work” game?
Unrailed: similar to uncooked, but a different kind of “work”
