How can i learn to play guitar without lessons?

i’m 17 years old and i want to learn how to play the guitar, but i don’t really have the time to take lessons…i saw a commercial on tv for the "i can play guitar" game for kids. i’d be really interested in something like that but i don’t know if it’s too small…i read that it was specially made for children’s hands…
anyways…please help.
