I think what they need is a combination of Pre-order bonus packs, like NV had + collectors items.
for the pre-order bonuses
Classic: (vault 13 armor and canteen 10mm gun and ammo and some stimpacks) and a water-chip
2 pack:( Sharpened spear, 2 antidotes 4 healing powders 100 worth of old world money 1 shovel 2 knives 3 Xander root and 2 Brock flower (or the east coast equivlent) and a "Type 1" geck
Tactical pack : 1 9mm sub machine gun, 48 rounds ammo 1 snack food 1 Nuka cola 1 Stimpack 1 Leather armor and a (Non Drivable) Tank
Brotherhood pack : Home made pistol. Shirt and pants, 4 bottles of Bawles Guarana*, and a steaming pile of [censored].
Capital pack: Unique 10mm "Amata" Limited edition Copy of Wasteland survivors guide(provids a weak buff while in inventory, 20 bottles of Aqua pura and a mini DC Capital building souvenir
Vegas Bennies Suit, Maria, ammo, 250 caps and a snow globe with the "platinum chip" in it
Note the Type 1 GECK, Waterchip, Non Driveable tank, DC Souvenire, Steaming pile of [censored], Waterchip, and snow globe are just decorator items
as for the Collectors edition, they already have PIPBOY version, they should add a version with everything in a Lunchbox, a version with everything in a "Geck" Case, a Version with the Classic Vault 13 Jump suit in sizes all the way up to XXXXXL, a Version with a 10mm lighter, a version of the 10mm built as a paintball gun, and a version of the 10mm that is a working 10mm pistol.
also the above in as wide a combination of individual comboes packs.. . for example walmart might get the Pipboy + GECK + 10mm real pistol, Gamestop would get the Jumpsuits and 10mm Lighter, ect ect....
*may have to further change the name..
