According to PCGH the normal retail version of the GTA 4 PC version can be installed an unlimited number of times. Online connection is required for activation. Disc is required for playing.
For multiplayer a Games for Windows Live account is required.
And they wonder why PC gaming is dying...
With copy protection like this I'd rather have a hacked copy.
And I'd much rather have it on PS3 than be lumped with this "Games for windows live" lameness.
DRM really is putting people off games.
It's not as bad as it could have been. They let you install it on as many systems as you want, which is good. That was the big issue with Securom. It's still absolutely useless and this game will be cracked before it's even released, as usual, but what can you do. Gamers voiced their opinions and these install limits seem to be going away. As long as Securom isn't doing anything else in the background (like keylogging, tracking webpages etc...) then I can live with it.
Now, if it is like Fallout 3 and Securom barfs up when it is in Vista 64, then I will be pissed. Games for Windows easy to use with Vista 64 my ass.
DRM is the biggest contributor for PC piracy.
The whole issue really is, why would you put with having to have the disc in your drive and more security measures with the retail version or just download the pirated version sans any such issues. The nice thing about PC games used to be no discs needed, not anymore it seems. Step back there in progress.
