Not saying the game isn’t playable, in fact I haven’t even started it yet. Mostly because I want to finish a campaign in another game first.
But in general it’s always a good idea to wait for the first patch, and there seem to be some issues, like the missing Ironman mode and problems with shooting from cover.
Now I wonder how long it will take for the first patch to be released. I realize nobody knows exactly, but are we talking about days, weeks, or months?
