I've given up on that sort of thing, needing a singleplayer game to always work offline.
Especially in games that I'll likely not replay more than once.
My main concern with RedFall is that I still don't know what kind of a game it is.
The recent Microsoft video did almost nothing to illuminate if it will have a significant story/narrative component, or if it's mostly a co-op looter.
It feels very directionless. But there is something there that could be cool if it has a good and chunky story element.
Unfortunately, we've not really seen anything.
Another thing I'm curios is, if you choose to play singleplayer, are you on your own, or do they intend for you to have AI controlled squad members. I hope it's the former.
