Hello I have been a long time user of xbox

Game and patch sizes have nothing to do with Xbox. As technology progresses, the amount of data that comprises a game will continue to grow. That's simply how big games are now. They have been that size on PC for years. If the data sizes are too much for
you, then you may just have to find a new hobby. I suggest hiking, or mountain biking, or knitting.

Is there any way to opt out of the patch and still play in multiplayer mode? My Xbox goes into an update install loop and gets stuck at preparing to download the update. Net connection is fine, everything else works except this one darned patch. It also
corrupted my previous install and now I've lost ALL my gamer stats etc for SE3

Then don't connect online. It won't download the patch.

But it's good that you realize that this isn't a huge issue for a lot of us. I mean 19GBs is really nothing nowadays and can be downloaded within 10 minutes. This is the direction the industry is headed. In your situation, I don't know what to say or what
advice to give. You'll find the same thing on the PS4 also.

That update is bigger than some games. Yikes! I wonder why game updates are so big now when they seemed so miniscule on the 360. It's not like the games are that much bigger...yet.

I played Sniper Elite 3, but never without the patch. A friend of mine who tried it said it was broken, unplayable garbage. Which is entirely believable considering the size of the patch.
