which game(s) that was sold on Steam but later removed you regret not having?

Divinity 2 The dragon knight saga! ;_; I still want it, even if I have the developer's cut

Mafia II and Wolfenstein (2009)

Neverwinter Nights 2 Platinum : I have disc version of base game and 2 expansions, of course GOG release too, but it would not bad to have another copy. I spent hundreds dollars and hours on this series.
Dragon Age II : I pre-ordered at EADM(now Origin)! I didn't know it was available on Steam at that time, what a shame...(facepalm)
