MysterD: Right, the version with ads, IIRC.
Kapela86: I didn't know, I haven't played it. But there's this:
"Install the AiO Unofficial Patch or The Suffering Widescreen Fix to remove the online DRM".
So maybe it will remove those ads.
According to a comment, the ads have been removed already years ago, but if you apply the AiO patch, it runs.
I tried it. Applied a German language patch, too...and it starts just fine.
Didn't really play now, only watched the intro movie to the point, where the actual gameplay sets in...works fine, the only slight complaint that I have, is that the mouse movement is a little fast.
The settings also didn't really help to slow it down.
But that's a minor gripe.
Edit: played a little longer...so far zero ads
(didn't expect 'em, to be honest), and the game runs fine
(Win 10).
