I've never been into figurines or even action figures but I have to admit, this one is kinda cool.
The pretty protagonist from Final Fantasy XIII probably deserves the respect and Square Enix's Play Arts figures are often impressive. If I was ever going to have a collection of figurines, I'd probably start with some FF-based characters (even if Lightning isn't my favorite). For those of you who are interested, this little collectible goes on sale in Japan this winter; it'll hold a price tag equivalent to $65. That seems a little steep to me but then again, I'm no collector.
Lightning will also be playable in the upcoming FFXIII-2, but she won't be the main focus for the majority of the adventure, or so we've heard. Either way, if you're a die-hard fan, to have her immortalized on your shelf might be a good idea.
