SpooferJahk: Untrue, just loaded them up myself right now and got these screens.

Redux DOES load, but with an annoying message that never goes away and a loading screen that is infinite.

Unless I am doing something wrong (I DID load both the PostalRedux.exe and the 64 Bit executable from within the binaries folder), these titles refuse to load without Steam unlike what RWS claims, which is complete bullshit on their part priding themselves on DRM-Free when only Postal 2 is.

African_wildlife: Sorry, you're actually right for Redux. The game did launch without Steam on release, RWS must have changed something. They probably wanted to make sure people understand that Steam is required for multiplayer or something.
