Pausable Real Time. An PRT is a computer game genre in which action happens in real time, but the player has an option of pausing to issue additional commands that are executed once the game is unpaused. This mechanic is mostly used in RPG and strategy games.
Synonyms: RTWP: Real Time with Pause
I like to challenge myself: I always play my PRT games in RTS mode.
