2K Games Transitions Legacy Titles to Steamworks or Drops Completely
2K Games will be moving over a number of games to Steamworks for online play, thus causing a number of them, including Borderlands and Civilization, to be unavailable during the transition. Other games, such as Stronghold 2 for the PC, and NBA 2k10 for the Wii, will not make the transition and online play will end for these games. Check the source for the full list of games either affected by transitioning or shutting down completely.
