- only run with Steam running (especially weird because the eddie refuses to run without Steam), and I can remember a statement from Larian that said something about the final version not needing steam after installation.
Follow the instructions
here to get a Steam version of D:OS running without the Steam Client.
I would also point out that this release is not only far from final, but is arguably still late-beta as it includes a lot of debug/error-logging code. Anyone looking for a smooth gaming experience should always hold off until the first public patch (and for complex RPGs, probably the third or fourth).
