We won't quibble over whether or not it should have been in the game to begin with (It should - Ed.), but rather delight in the fact that Firaxis have responded to overwhelming requests for live local multiplayer by sticking Hotseating into the next patch, currently slated for June/July. Have a gander at the full blurb for the official 2K Forums:
The time has come to reveal the “much-requested addition” that I teased you all with in the most recent patch notes.
Hotseat is coming in the next big patch, which is currently slated for a June or possibly early July release.
For those of you that do not know, Hotseat is a method of playing multiplayer where multiple players take turns on the same computer. When one player’s turn is over, they get up and let the other player sit down to play their turn. We’ve received many requests for the ETA for this mode being added to the game and so I’m very happy to get to bring this to you guys today.
Also, this patch will contain far more than just Hotseat. The other details of the patch will be revealed in the future, but I wanted to get you guys this big news as soon as I could!
The number of commenters who've posted following the announcement saying 'Yay...now I can play with my wife/son/husband/daughter' is frankly quite heartwarming. Gaming...bringing folks together.
