Exactly like steam, it comes up with the store tab first by default, but that can be changed in the settings. If anything it's less ad heavy, there's no equivalent of the "steam news" ad popup.
Actually he's referring to window popups when you launch a game, I've seen it happen as well. I was able to disable in the Origin settings however and by the way, the Steam news ad thing can disabled in options too.
And anyone else here screaming "I wont buy your stuffs EA!" Is a fuckin liar too. You'll do whatever they tell you to do in order to play your shiny new BF3 and you'll like it. Stop lying to yourself.
This is kind of a dumb comment for many reasons but just a few: the Battlefield franchise is certainly popular but it doesn't enjoy the kind of assured success that Call of Duty does. I love Battlefield games but several instances of bad news related to this game has me rethinking buying it at all. There are a ton of good games out this year and 2 other major FPS games that I know of so I'm not really beholden to play this or something.
