Since the beginning of this year Nintendo's been offering a new selection of games for Club Nintendo members every month in exchange for coins, which are acquired by registering games and taking surveys, among other things.
The first game they offered that way was The Legend of Zelda: Majora's Mask, a true classic that got everyone's attention, which no doubt was there intention. Since then the games on offer have been somewhat less exciting.
July's Club Nintendo games are a step in the right direction, though: Mario Tennis for N64 and Electroplankton for DS, downloadable to the Wii and 3DS, respectively, for 150 or 100 coins.
Mario Tennis is definitely another classic, while Electroplankton is a weird little DS title with some musical leanings that'll nevertheless provide a great deal of amusement to 3DS owners.
If you don't have enough coins to snag both, why not go buy some new Nintendo games, like Pokemon Conquest or Xenoblade Chronicles, to reap the rewards? It's a win-win. Let us know what you think of Club Nintendo in the comments or on Twitter.
