I rarely do. Although the last one, was like 6 months ago when i bought the Command & Conquer Collection.

This O_O

Well I have Wasteland 2, Pillars of Eternity, and Torment: Tides of Numenera all coming in boxed but before that I bought a boxed copy of Wrath of the Lich King.

Battlefield 2.

Either Darksiders or Arkham Asylum. Don't really remember.

Warcraft battle chest

Good question! Many years I prefered the retail versions, even if the digital version was up to 10 € cheaper. But since most retail games are bound to an account anyway and my game shelves are full, the digital version was "good enough". The absence of well designed handbooks or other nice goodies didn't help to keep my interest in retail boxes.

My last retail PC games:

2012: DiRT 3, Haunted, Rage, Lego Harry Potter 2, Batman: Arkham City, Assassin's Creed: Revelation (Ottoman Edition), Deponia, Lost Chronicles of Zerzura, Mass Effect 3, Captain Morgane, Yesterday, Diablo 3, DiRT Showdown, Memento Mori 2, Chaos on Deponia, Secret Files 3, Jack Keane 2

2013: Crysis 3, The Inner World

2014: none

The last retail PC games which were totally worth it:

Starcraft 2 Heart of the swarm collector's edition

That's awesome. Wonder how much that costs now.

Ebay seems to have them around $10-$15 each which aint to bad.
