Linux (plus other unix and unix-like) exclusive here; I actually don't mind "cross-platform" for "console A or console B", but describing a mouse-and-keyboard game as "cross-platform" implies it works on other mouse-and-keyboard platforms, which in practice amounts to either OSX (which... sucks, basically) or unix (linux/bsd/etc tend to be compatible enough that you can get anything from one working on another with enough hammering).

Well "games that run on both PC and console" works, but it's a bit unwieldy.
