Summary: Wii Sports Club is essentially the same as the original Wii Sports but with improved graphics, improved modes, and improved controls. It also has online play which is a dream come true. I recommend using the Wii Remote as it makes the offline and online experience much more fun and active. If you've got room, $35 is a steal for such a simple, fun, active game.
Summary: I love Wii Sports, but after I tried out the free trial on the E shop, I gave up on this game. If you have Wii Sports, DO NOT BUY THIS GAME. It is just Wii Sports+ HD+ Online. If you don't have Wii Sports, go ahead and buy it if you want to.
Summary: I've played all of these games before, if you've owned an original Wii, you've played these before also. The only difference is that there is online capabilities. You join a "club" and then random posts pop up while you play. I'm not sure that having an online match is worth the cost, but to some, it might be.
