The only ones I haven't played PS versions of are II, III, and V
III sort of because.. well... it didn't have one.

The other two because they didn't seem amazing during the first 10minutes, and I played I, IV, and VI instead... and hadn't got around to going back to play them.

(I got Origins, Chronicles and Anthology all around a similar time frame.. so was kind of a frenzy for a bit then a burnout....)
