Executor Super Star Destroyer Launches at 136.5 cm Long
Lego released the Star Wars Ultimate Collector Series Executor Super Star Destroyer (75457) on 1 October, and at 136.5 cm (53.5 inches) it is the longest Lego set ever made. It has 6,130 pieces, seven minifigures and a price of £649.99 / $799.99, which works out at roughly 13 cents per piece in the US.
Brick Fanatics gave it 9/10 after a build of around 12 hours around a Technic skeleton, although it found some exterior panels flimsy during assembly. Buy before 10 October and you also receive the Darth Vader’s Lightsaber (40897) gift with purchase, while the set itself is excluded from this week’s double Insiders points on Star Wars.
Our take: The reviewer’s biggest complaint is the one we would worry about too, which is where it lives. Measure your shelf before you order, and if the answer is nowhere, our guide to baseplates, tables and display solutions is a useful place to start.
Downton Abbey Becomes the Largest Lego Ideas Set Ever
Ideas set 21373 Downton Abbey also went on sale on 1 October, priced at £269.99 / $349.99. The model of Highclere Castle has 4,711 pieces and 13 minifigures, making it the biggest Ideas set Lego has produced.
Why it matters: At £269.99 it costs well under half the Executor, so for many builders it is the more realistic centrepiece purchase this autumn.
34 Video Game Sets Retire on 31 December, Including 14 Minecraft Sets
Video Games Chronicle reported on 29 September that 34 video game sets leave the range on 31 December. Minecraft accounts for 14 of them, followed by six Sonic, four each for Super Mario, Animal Crossing and Fortnite, plus one Horizon set and one arcade machine. Most are aimed at younger collectors rather than the premium builds that dominated earlier retirement lists.
The Minecraft group is the one to watch if you build across both worlds. Prices run from £8.99 for 21266 The Nether Lava Battle (99 pieces) up to £89.99 for 21279 The Enderman Tower (867 pieces). Lego also cut across its usual price tiers, so there is something for every budget.
At the larger end, 21278 The Pillager Outpost and Ravager is £74.99 for 665 pieces. 21273 The Ghast Balloon Village Attack and 21282 The Parrot Houses are both £59.99, at 555 and 535 pieces. 21270 The Mooshroom House and 21272 Woodland Mansion Fighting Ring sit at £44.99 each, with roughly 500 pieces apiece.
Smaller sets suit builders who want parts and scenes rather than a display piece. 21584 Nether & End Portal Journey (£12.99, 192 pieces), 21267 The Illager Desert Patrol (£12.99, 105 pieces) and 21268 The Baby Pig House (£17.99, 238 pieces) are easy to fold into a larger layout. 21274 The Warden Encounter, 21275 The TNT Jungle House, 21269 The Armadillo Mine Expedition and 21277 The Pickaxe Mine fill the middle, from £17.99 to £49.99.
For crossover builders, the draw is that these sets sit naturally beside custom work. The Nether, jungle and desert scenes give you ready-made biomes to extend, and our guide to building Minecraft biomes with Lego covers the scale and design choices involved. The Enderman Tower and Pillager Outpost are the tallest builds here, so they work as anchor pieces for a themed shelf.
Why it matters: Retired sets typically climb on the resale market once stock runs out, though retirement dates can shift. If you collect Minecraft, our complete Lego Minecraft collection guide works as a checklist. Prices above are Lego’s UK list prices.
Nineteen Ideas Projects Reach 10K in Two Weeks
The third 2026 Ideas review period has produced 19 projects at 10,000 supporters within its first fortnight, according to The Brick Fan. Seven were added on 26 September: Subaru Impreza WRC & Colin McRae, Plaza Mexicana, Supernatural, The Hunger Games Saga Diorama, Kodama (Tree Spirit from Princess Mononoke), The Enchanted Winter and Tentacle Rock.
Why it matters: That is close to a fifth of the projects expected to qualify this round, and only a few will become sets. Our 18 September roundup on the Executor release date and earlier Ideas milestones shows how the round has built up.

- BrickLink Designer Program Series 9: Pre-orders open on 6 October at 4pm BST and close on 12 October at 11pm BST, with five sets from Pumpkin Patch (£44.99) to Fisherman’s Village (£319.99) shipping around March 2027. We covered the Series 9 reveal earlier in September.
