I am still confused about Dead Space 1 - Origin version (yes, it is a bit OT but it's still about free copying). Whenever I try to start an Origin game which needs Origin, the Origin Client will be started. This is not the case if I try to start Dead Space from any directory. The game runs without a problem. It still does run after I deinstalled the Origin Client and deleted the keys from the registry. I've tested this multiple times on winxp. But here it was said that the game does not run without Origin. Since the Steam version DOES need the Client in any case I think this would be an alternative but I am still not sure why it does workl for me but not for all.
When I tried the Origin version of Dead Space, it certainly did require Origin to play. Without running it through Origin, I even got an Origin-specific error popup that's built right into the main program file. The Steam version requires Steam to run, but it doesn't have CEG or any kind of activation limit the way Dead Space 2 does, so I'm comfortable with playing that version.
I WISH I could get the Origin version working without Origin, but I've tried everything I can think of, and it just won't run without the client. :( Is your game fully updated, or is it an older version?
