Far Cry Collection doesn't require online activation despite the blurb on the back saying that it does (Thus new retail copies of Far Cry 2 no longer need to be patched of their DRM). World in Conflict Complete also doesn't require online activation (The Soviet Assault expansion, which was released on 2009, never had any DRM whatsoever.)
Both are a little old for this list.
I would also like to ask about 2 specific games: Alien Breed Trilogy
and Shadow Warrior
. Does anybody happen to know whether those 2 games require Steamworks to play? While Mastertronic does mention that Steamworks is necessary for Deadly Premonition and Alan Wake's American Nightmare, there is absolutely no mention of it on Serious Sam 3, despite the game being Steamworks only.
Alien Breed Trilogy requires Steamworks.
That's interesting about Shadow Warrior though, I had no idea a retail version was coming out (I bet they're not even going to bother trying to get a USK rating for it here in Germany, or else they may end up only speeding up the blacklisting process). DRM-free versions have been released already, so DRM-free is not unthinkable, although the same could have been claimed of Giana Sisters, the retail version of which ended up being infected by Steamworks. I'll certainly keep an eye on this.
