Tagline/Slogan?

I keep wanting to store these somehow, because they're usually vaguely important for the image the game is trying to deliver or relevant to the plot, gimmick, or some other major feature of the games.

So, any idea where to put these? I've so far used editor notes for them, but that's only because there's nothing better that I could tell.

Examples:
* Crysis 1: Adapt, Engage, Survive.
* Crysis Warhead: Adapt, Engage, Dominate!
* CoD:AW: Power Changes Everything.
* Enforcer: Police·Crime·Action and Justice·Law·Order

EA and Activision especially like these. These are also often part of the subtitle as seen with Enforcer (though that could easily be plain subtitle).
