My kids (15, 12 and 9) prefer Toy Story, and I do as well. The biggest difference to me is that at TSMM, I know what I'm shooting at. I know which dart or egg or ring is mine, and I can see where it's going. Those little red laser dots - not at all. I can never figure out where I'm aiming, which dot is mine and whether I've hit anything. Plus if one person in the car at Buzz is shooting and the other decides to spin the car around to aim in the other direction, the first person (assuming they could figure out what they were aiming at anyway) would miss. I also think the "games" at TSMM are more fun - better than shooting at a bunch of Z's. The one thing I like about Buzz is that the lines aren't as bad.
