Looks like Ubisoft has admitted failure, now that it appears they have removed the core part of their controversial DRM, the need to have a constant connection to their servers.
Patches for Assassin's Creed 2 and Splinter Cell: Conviction now only does an authentication check on game start-up, and will no longer boot players back to the main menu, and perhaps losing any unsaved progress as a result, the second it detects that a connection to their server has been severed (whether it's because of your flaky Internet connection, or their flaky servers ... it's almost never because you're pirating their game, because the pirated version has this DRM removed).
This comes after Ubisoft decided not to use their controversial DRM on their recent game, RUSE.
So has Ubisoft really abandoned their stupid DRM, one which never really stopped piracy?
