Additionally games at this point are effectively incomplete and "Day One Patches" are leveraged to get extra time to fix bugs.

Now mostly this is leveraged to finish up the online features (ie. pvp), as one obviously can't play online without connecting to the net, and then that's an opportunity to download a patch. However, these patches do have other fixes and surely there are some companies that are leveraging this significantly more than others for general fixes that have nothing to do with online features.
