Brittany is an avid Sims fan and has been playing and modding the games since the first Sims title was released in ! Source "Mods," short for modifications, are user-created files which modify or add more to the regular game. Since Sims 2 was released, fans have been creating mods and sharing them online. The options for mods are pretty diverse. I've seen everything from one for The Sims 2 which added horses to the game and yes, Sims could even ride them— and this was way before the Pets expansion pack added horses to The Sims 3 , to one for The Sims 3 which added in a working ferris wheel. Some are much less complex, just restructuring the regular game files to add in or change things like a Sims 3 mod which allows late night bars to stay open 24 hours instead of closing at 2 a.
