Two of those games (Dirt 3 and one of the Flashpoints) use GFWL. Codemasters hasn't said whether or not they'll remove that crap before it shuts down.

There's a good chance Dirt 3 will have it removed since there's a new version of the game on Steam's internal database. But Operation Flashpoint? Who knows. Codemasters has a nasty habit of letting games and licenses die out and not giving a fuck, so buyer beware.
