Being "deep" and being "utterly cliche" can often be one and the same.

I've no intention of buying an XBox 360 unless they have enough games that I wish to purchase. One decent RPG isn't necessarily enough for me, but if they get a good amount of Xbox-only titles, sure, I'll get one. After I buy a PS3 and probably after I buy a Revolutions. You buy the systems that have the games you want.
