I don't like forced auto-patching as well, and for a series of resons.
First of all, the Internet connection in my zone is worse than awful, so I often needed hours and hours of download just to be able to start a game I have purchased. That's why I usually bought only retail games, DRM-free or not... yet, during the last few years this has become useless as well, since patches are too many and too big to allow the disc to make a difference -and that is not counting ridiculous examples like MGS V and its disc containing only the glorious Steam installer.
Another shiny example is when the patch breaks the game; I remember that the Italian copies of Mass Effect 3 have been compeltely broken by a forced update on Xbox Live, and I had to wait for a week before I was able to start the game again (the starting menu continuously crashed, forcing an hard reset).
Also, without forced auto-patching, you can keep the version you prefer without the risk of content being retroactively cut -as it has been the case with Steam copies of one of the GTA games, where some of the music licenses expired na dhave been removed. By Bhaal, if I bought a game in a certin state I demand (as is my right) to keep it that way! It would be just like deleting a track from a music CD because the rights for a cover song are no more.
People may say what they want about the messy Galaxy, but whoever thought about the rollback feature should get a medal.
On a side note...
Smannesman: At least with DRM-free games you sometimes never get patches and if you do get them (often) much later.
Jeez man, give us some pause! :P
I undertsand that you are upset with GOG (and for good reasons, btw), but your continuos anti-GOG sarcasm in every thread has become very stale. Almost as annoying as "I have it elsewhere, so I'll pass! :D™" or "Vote for X"!
Please, bring back the Smannesman of old with their menaingful comments!
