Time compression

Related:
* Time shifting
* Bullet time

Limitations:
* Full pause is not in the scope of this tag, see active pause or consider it regular pause functionality.
* Sleeping or other "loitering" functionality does not count as time compression as player is often ignorant of what's happening and/or incapable of cancelling it midway.
* Not related to time shifting, the other tag is more in terms of something in the gameworld rather than external game functionality, although time compression can be masqueraded as something in-game as well (in X-universe it's a device that distorts passage of time for the pilot).

Notes:
* Possibly started in (space) flight sims.
* Often present in tactical games, alongside active pause.
* This may include half-speed which gives the effect of permanent bullet time. Bullet time is not applicable for these, however.
