Vampire Survivor, Last Epoch, Path of Exile, Victor Vran, Adventures of Van Helsing, Wolcen, Warhammer Chaosbane, etc.
I've gotten into Diablo style ARPGs and trying them all. So for Last Epoch is the funnest for me, primarily setting wise but PoE is fantastic, just soooooo many systems to figure out.
I've been using Atomic stuff for a while. First Silverblue but now I use Bazzite Gnome.
I actually use Nix ontop of it for dev tools and CLI tools that Flatpak doesn't handle.
I don't like the toolbox style of doing things. Nor devbox, dev containers, nix shells, whatever. Too much hassle.
But I do like using Nix + Home-manager to manage my home directory and tools, especially between computers as it's all in a git repo and has separate configs.
