Square Enix has launched a feedback survey for those who played Final Fantasy XV

Currently only available in PAL territories, though a rollout is expected, filling it in should take 10-15 minutes and unlocks three exclusive Final Fantasy XV wallpapers created by the dev team. As you'd expect, the feedback will then be used to improve the finished product. The survey closes on May 31.In order to provide feedback via the survey, you need to complete the product registration process via Square Enix Members After nearly a decade-long wait, we finally got a chance to go hands-on with Final Fantasy XV at PAX East 2015, and we're happy to say that it looks like the wait was worth it. Mitch Dyer and Marty Sliva went back and forth on how much we loved the new action-oriented combat system , while Luke Karmali dove into what makes Episode Duscae so special. Meanwhile, the latest Final Fantasy title, Type-0, arrived recently. To check out whether or not it's worth your time for more than the Final Fantasy XV demo, check out our review
