I've been thinking (and doing the math), and it appears that getting two Vaults and a few select Add-Ons might make more sense than getting one Vault and the Worldbuilder Bundle (obviously "make more sense" depends on what you value more). Worldbuilder has all the Trays of Terrain (ToT) and Pouches of Mini Things (PoMT), as well as the Wooden Dice Tray. Getting this and the Vault (without the Carry Case) is $460 ($110 + $350). The Vault contains Starter Terrain for the Dungeon, Village and Wilderness (there are a few unique pieces in the ToT boxes, and a few alt-colour schemes, but mostly appears to be duplicates). The Vault also contains all Minions that are also included in the PoMT - Minions (with the only exception being Brown Kobolds). The Vault also contains over 800 Standees, plus sleeves and bases. Getting 2x Vaults, along with the ToT - Graveyard, ToT - Ruins, PoMT - Undead, PoMT - Cavern, PoMT - Aquatic, and the Wooden Tray, all comes to $425 ($110 + $110 + $50 + $50 + $20 + $20 + $20 + $45). (This means not getting the ToT - Dungeon, ToT - Wilderness, ToT - Villages and PoMT - Minions) The trade-off (other than he $35 difference) appears to be this: You lose Brown Kobolds, some unique terrain pieces and some alt-color schemes (for both minions and terrain). You gain double the amount of all creatures (including Dragons, Giants, all the Heroes, every other colour of Kobold that isn't brown, etc.) and double the terrain that are already included in the Vault, plus extra bases and sleeves. Final numbers of certain creatures and terrain might not be the same either - some go up, some go down... For example, you'd have 28 (8+8+12) Zombies instead of 20 (8+12), 5 (1+1+3) Umber Hulks instead of 4 (1+3), 7 (3+3+1) Trolls instead of 4 (3+1) - but on the flip side you'd have 4 (2+2) Orc Spearmen instead of 8 (2+6), 6 (3+3) Helmeted Town Militia instead of 9 (3+6)... Without knowing exactly what are in the ToT for Dungeons, Wilderness and Villages, it's hard to say exactly what would be lost, but 10x10 Base Tiles seems to be the biggest loss (you'd get 4 instead of 6, if the images on the campaign page are an accurate reflection of contents). Am I missing something? Is there anything in the Dungeon, Village or Wilderness ToT's that would be more enticing than two of each Dragon?
