What religion are you if you worship only Lord Ganesha?

Is it ok to worship Lord Ganesha alone? Truth be told, I am not "drawn" to any other of the deities in the Hindu patheon, and I did not know if the worship of Lord Ganesha alone would still qualify someone as a practicing "Hindu", or if it would fall into a more Pagan/New Age sort of practice? Like I said I am just not drawn to the other deities and I find strength in Ganesha. Is there a religion that worships just him?
