One of the really nice things that C:S does is that it has built in mod support via Steam. Unlimited money is an option straight out of the box, and opening up the entire grid is a Steam supported mod.
As far as sporting events, I don't think there is anything like that. The game is very minimalist when it comes to personality, unlike the Sim City games. There's some special buildings built into the game, and a boat load of buildings in Steam's mod section.
