The Black Friday deals are thick today, and if you don't mind pouring a few bucks into the black heart of EA, there are deals to be found via its Origin store. Among them, the biggest names have gotta be the brand-new Batman Arkham City game for $24.99 and Battlefield 3 for $29.99. That's half off of each.
Other deals of note include Dragon Age II, Batman Arkham Asylum, and NFS Shift 2 Unleashed for $10, Mass Effect 2 for $15, and Crysis 2, Dead Space 2, and Bulletstorm for $20.
For what it's worth, I'm having some trouble locating the best deals on Origin's website. Things seem to be easier to find via the executable Origin client. (Dun dun duhh!)
Also, those of you who are used to a relatively smooth experience on Steam will want to brace for possible issues. I've owned a copy of Shift 2 Unleashed for a while now via Origin. It shows up in my library, and I can download and install it. However, the game key from Origin is rejected as invalid in the activation dialog when the game is first run. Never happened to me on Steam, but EA's service still has some quirks, it seems. Still, these deals may be worth a few headaches.
