The title Toy Story pretty much says it all. This movie is literally a story told about and by toys. Sometimes simple is good.

Other titles that were floated for the movie before the folks at Pixar landed on Toy Story were Made in Taiwan, The New Toy, Moving Buddies, and Toyz in the Hood. That last one doesn't sound real, but we suspect that it'd be a pretty great spin-off idea. (Source)
