Nintendo has released a series of downloadable Coin Rush expansion packs for New Super Mario Bros. 2 for the Nintendo 3DS in the past few weeks, and while so far all of that content has consisted of fresh material, the developers are giving the people what they want with the new Gold Classics Pack which is made of pure nostalgia. This new DLC is loaded with familiar levels from the original Super Mario Bros. and Super Mario Bros. 3. World 1-1 from the classic game is in place, of course, but some less commonly revisited stages such as 4-1 also make an appearance in updated form as well as SMB3's own World 1-1. The company's latest Nintendo Direct explains it all and notes that this pack is free to download for a limited time. Pick it up from within the game itself between now and the end of January 2013 and you won't pay a single coin. Unfortunately, you cannot apply those unspent coins to your Coin Rush score.
