==官方论坛== The complexity of the games often warrants player collaboration over the forums. Often, players will assist other players with the games, post modifications, and write "after action reports". Due to much of the game content being in plain text and image files, the modification of the games has become very popular. Much of the gameplay information used by the engine is contained in uncompressed text and bitmap graphic files. The ability to freely edit these files has allowed an active modding community to develop. After action reports, usually abbreviated as AARs on the forums, provide a way for players to discuss their own gameplay in unique ways with other players. AARs are reports written by players about their experiences with a game, ranging in style from simple presentations of the development of the game with screenshots to highly embellished character-driven stories only loosely based on the events in the game. They are generally serialized in a forum topic, with every update post corresponding to a period of gameplay, and with comments and suggestions made by readers between updates.
