According to the PlayStation blog, everyone who preorders LBP3 for PS4 - through any outlet, either digitally or in person - will receive a variety of game-crossover costumes, most notably a set based on characters from the forthcoming Dragon Age: Inquisition.
And for further DLCs, that's where you'll have to decide which retailer you'll be place your preorder with.
Preorders at Gamestop will net you a "Mythical Creatures" in-game costume pack. Best Buy will be giving out "Hidden Creatures" costume packs with their preorders. And finally, Amazon's exclusive costume pack is "PlayStation Favourites," featuring costumes of characters from other PlayStation games such as Journey, Patapon, and Jak and Daxter.
Preordering at Target is probably the best option for those looking for physical rewards, as doing so will net you your own Sackboy plushie, complete with a vaguely dorky Target hat.
If that real-life business is not your thing, don't worry; preordering a digital copy of LBP3 through the PlayStation Store will entitle you to download the Instant Access LBP3 T-shirt pack. That means you'll be able to wear the in-game shirt in LBP2, LBP for Vita, and LBP Karting - and, of course, in LBP3 upon its release too.
The above incentives are for North America only, but the European bonuses will be announced soon. LittleBigPlanet 3 will be released on both PS3 and PS4 on November 18.
