I'd buy this game if it wasn't given for free...
Gameplay: Every game, besides golf and boxing have amazing gameplay mechanics... My buddy who plays tennis played like he really does on the court, and the ball reflected his moves exactly.... Some reviewers say that it doesn't go in the right direction...etc..ect.. but maybe they aren't hitting the ball right?... or maybe they blew off the training?.... Baseball reads swings (nearly) perfectly and bowling is simply flawless.... By far the best game... You can control your spin, speed, and even lob the ball in the air halfway down the lane if you'd want to... Boxing however is embarrassing... it rarely reflects what you are actually doing, however, the computer is so easy (until you get to pro) that it won't even really matter....
Graphics: People complain that the graphics are cheap and doll-like... Well let me tell you, those are some shiny dolls... The Mii's uniqueness and originality make up for it's uncomplicated textures and polygons... The graphics in all the games are nothing to frown upon, while they are not spectacular, they are notably better than the GCN's... The bowling balls are really shiny also... :P
Sound: Three words.... Cute little jingles... although they seem annoying at first, you'll be humming them before too long... the tennis racket hitting the ball sounds like it should, and so does the pins hitting each other after bowling at them... Same as the graphics department... far from groundbreaking, but the sound fits perfectly with the kiddish mii's and simplistic gameplay...
Value: Although this game can't be played (literally because you'll be sweating so hard) for hours, it is perfect if you get stuck in a dungeon in Twilight Princess or if you have some friends over... I'll still be playing this game as long as I play my Wii... and because it's free, it gets a 10 in this category... I'd pay for this game if I had too...
Reviewers Tilt: 8.5 rounds to a 9 :P ... People seem to forget that Wii sports isn't an all out game (only 3 innings in Baseball, 3 rounds in Boxing, and 9 holes in Golf), however it isn't asking for an all-out price either... It is the perfect way to learn how to use the wii remote...
Hopefully Nintendo will follow up with a Wii Sports 2 with online play and full fledged games, but if not, I'll still enjoy this amazing game for months to come...
