Final Fantasy XIII is old news, especially since XIII-2 has corrected most of the problems that stopped the original from realising its full potential. However, ShopTo's Xbox 360 deal will net you a lot of swag for your money, including a hardback art book, soundtrack CD, art print and a decal.
Right. Well then. Here we go. Final Fantasy XIII succeeds at inspiring an emotional response in everyone who plays it (as works of art should)... but these are often intense feelings of anger, frustration and bile. The graphics are great and the latter half of the story is well-paced, but it's unfortunately prefaced by a massive slab of grindy bullsh*t. I think I'll settle for "divisive" and let you settle this amongst yourselves.
Joint-PS3 owners should definitely opt for the graphically superior version.
