missing the steam client.
So much to do there though: 64bits clean, not crashing without dbus, not bash but sh scripts, removal of the 32bits legacy code, pure and simple ELF64 application (static libstdc++ and libgcc) libdl-ing everything from the system (to maximize distro compatibility, but then a fork of libstdc++ is needed: usual c++ toxicity), wayland->x11 fallback, vulkan->gl->cpu fallback (that said the 64bits steam client is libcef from gogol, then certainly with all those fallbacks already there).
