Yes, and it'll be a factor until I can be assured that they've changed. I'm still waiting for my copy from Amazon, so if Halo 5 (or any of their games in the next, let's say, 7 years) isn't both basically bugless and very fun, then that will mean a hard choice, a choice on whether I want to stop dealing with 343 Industries, and I'll probably get out if it comes to that.

I'd like to point out (again) to all the people saying campaign was fine-- it was not fine, it had problems too, and it still does.

In increasing order of significance:
- Halo Anniversary and to a lesser extent H2A remastered graphics have added z-fighting
- H1A has noted geometry issues
- inability to save films (applies to Halo 3 and ODST campaigns)
- inability to have original sound effects in Halo 1 regardless of settings
- Halo 2 classic music and cutscenes are oddly muffled
- terminal videos need Halo Channel and an Internet connection to play
* (Halo Channel has been known to just not work for no apparent reason even after quitting)
- the game can and will completely crash while playing campaign normally
- various new glitches, including some that can stop you from playing the rest of a level
- losing your saved game (fixed?)

These are not things to be brushed off. If you didn't experience or notice them, good for you, but I've had all of these affect me except a lost game save and so have a lot of people.
