DelusionsBeta: Here's my beef with people saying GfWL is less harmless DRM than Steamworks, now that it's mandatory online checking. We don't know the limit. I know there was much hoo-hah about Bioshock 2 having a GfWL-applied 15 install limit, and I've also heard that it applies to other GfWL games that don't lock onto an account.
I understand that GfWL divides games into two classes.
1) Game is registered to one gamertag only, unlimited installs.
2) Game is not limited to one gamertag, but has limited installs.
While I don't have any evidence for this other than What I've Heard, I understand the developers that use it are in a similar position. At least with Steam, you know what you're getting in for if you see Steamworks on the back of the box. No such luxury in GfWL.
Until Dead Rising 2 though you didn't need to activate to play, making activation limits pointless and not a real concern. If there is a limit on the "release day check" for Dead Rising 2 though, then that sucks and is worse than Steam by far.
And contrary to what Gersen says I am pretty sure I had to put my serial code in to activate the release day check thingy.
