I've played about half way through the single player campaign with no problems, and a couple hours of multi with only one client crash immediately after loading a map once. Seems plenty stable enough to me. Maybe if I played it 24/7 I'd be running into more of the problems, but I ain't got time for that.
I think this game was worth the $48 I paid for the single player alone. Even though it's really short, it's fun and the graphics are just amazing. Definitely a level beyond anything I've seen to date. I'm enjoying the multi a lot too.
Between BF4 and DCS, I finally got motivated to pull the trigger on a new PC for the first time in over 4 years. Yeah I could've made do with this one for another year or two but what the hell. I want to crank those settings at 2560x1440 and have some anti-aliasing again.
