The ones I care about: V, VI, VII, VIII, IX, X-2, and XII. I don't play MMOs so I will never play XI or XIV. I don't have a PS3 so I can't play the XIII trilogy. I won't make sequel or prequels a priority so I might never play them except for X-2. For some reason I single that one out, and it can act in place of XI. So I'm good with that.
