Ballistics

See also: overpenetration (technically part of ballistics but often treated separately)

Aspects:
* Gravity affects projectiles - bullets/arrows drop with distance rather than flying in a straight line unaffected by gravity
* Drag or air resistance - projectile speed drops with distance traveled, may affect only effective range of the weapon but may involve reduced damage/penetration properties
* Wind shear - wind blows projectiles off course
* Overpenetration
* Ricocheting
* Overmatch
* Materials

Common in tactical shooters, some others also use it to improve realism.

For strategy games this can be assumed to indicate the game simulates the flightpath of the projectiles rather than doing hitscanning (and does this to see if the projectile actually hits, not just for the graphics).
