+if not listed there) with also the release year included as `games.release_year`. 
 If there is a mod that needs to be added (or it adds the support for server
 queries for the game), its name should be composed of the game name, a separating
 **bracket**, the mod name and the release year as specified previously
-(e.g. `Grand Theft Auto V - FiveM (2013)`).
+(e.g. `Grand Theft Auto V - FiveM`).
