Buy-to-Play, abbreviated as B2P or BTP is a revenue model for games that can only be installed and played once purchased. Not to be confused with subscription-based games that limits access based on time, buy-to-play games can be accessed for an unlimited amount of time after purchasing. Some of the games listed below offer free trial periods.
