Drives are a mechanic used in Inverse World, Worlds of Adventure, Unlimited Dungeons, Homebrew World, and other hacks. Drives can be customized into a component for other DW games to replace alignment. Typically the End of Session move is edited to award XP for acting on a drive rather than on an alignment.
