Mercenaries: Playground of Destruction
Mercenaries is a good game, and I had quite a bit of fun with it. But Red Faction: Guerrilla did most of what Mercs does, better (technical hiccups aside) - so it is hard to go back to it, now.
I may return to Mercenaries at some point, if I run out of open-world destruction games to play, but that's seeming less and less likely anymore.
