I have to agree with those questioning the maturity of the OP. Whining and complaining about this game, but claiming to "love sports" leads me to believe that you either know very little about sports, or you just suck at them. I think bowling is the most user-friendly game on the disc, because it's the most reflective of its real life counterpart. If you can't learn how to roll the ball straight, you have problems.
Baseball is ridiculously simple for anyone who knows anything about the sport, and possesses the ability to learn timing. I beat the computer 7-0 with the mercy rule after the 1st inning and have thrown several no hitters. Learn the sport.
Tennis is insanely fun. Pretty accurate to tennis in real life, but it does take a little practice. I pulled off a nice come from behind win today, winning 3 games in a row after losing the first 2.
Golf is one of my favorite games because in my opinion, it's the most challenging. You can't just go up there hacking. You have to pay attention to the direction of the wind, and where the traps are. I sunk a 40 foot putt for a birdie on a par 5 today and felt like I was Tiger Woods. Awesome feeling.
Boxing, eh, well...I LOVE boxing, but unfortunately, I'm much quicker than the system. I duck and throw a hook to the body, and I'm lucky if I can get my Mii to throw a straight jab. It's unresponsive, but once you adjust for it, it can be fun. Just not all I'd want it to be.
In conclusion, Wii Sports is leaps and bounds better than I ever imagined it would be. I think it truly shows how amazing the Wiimote can be. Half the time, I'm having so much fun, I don't even notice that my Mii doesn't really have arms, or he looks like a bunch of shapes thrown together. It doesn't even matter. The game just provides a good time.
