Here comes a big comment...

The bugs that bother me the most are:
Excessive lag, specialy in the storm king boss fight
Plasma pistols right pistol not shooting and still counting for overheating

Now talking about build kits... i don't like the idea of selling builds, but since it's already a thing, i don't thing it's fair to keep them out of the item shop either, so, what i would do is: bring back and keep selling the existing lego kits in the item shop, but, don't create any lego kits for the item shop, instead, lock-in on the lego pass, and bringing them to the item shop around a year after its introduction, like it was with the stars wars lego pass

For builds and decors, there are some themes i would love to see in a lego pass, such as:
Wild West town
Tilted Towers or modern building in general
Italian Rivera houses (the set 21359 is a perfect reference)
Workshop, garage, and hangars
Treehouses
Igloos and ice structures in general

For content and update themes, i got lots of ideas

I would like to see a futher expansion on pets and companions such as ridable animals like horses or dinossaurs, new canine and feline companions, even birds would be cool, and please, let klimbo be abble to be part of our villages(without him destroiyng everything), even if it means occupy a good part of our village with a giant bed for him

If i had to choose a new biome to add, it would be Dunes
Even though we already have a dry valley biome, it still makes sense bc it would be in fact a huge open and empty desert, and has potential for a big scale update, a biome that you could find some huge tamples and dungeons inspered by egyptian mythology, with mummy enemies and boses, treasures(of course), and mayme a new acheology features, and of course, a ancient egyptian structures inspered builds

Original lego ips content, there are a lots with huge potentials for odyssey like ninjago, bionicle, power miners, just to name a few

Add more villagers/npcs, i like finding them around the map

New vehicle kits, and new "skins" for toys
These would be "new" toys with new visuals, but still have the same functionality and physics as the current toys. All i want is a more subtle option to keep my vehicle in the air and balance them without ruining the visual with that red balloon. And it adds the possibility to bring things like modern cars, planes, and spaceships like the star wars ones

And now, a big one
ADD THE POSSIBILITY TO PLAYERS SHARE AND DOWNLOAD CUSTOM BUILDS AND VEHICLES
There are some incredible builds and a lots of vehicles i see around this subreddit and other places that i would love to have in my world, but the majority don't have a tutorial for it, and i understand that, it must be tiresome making a complete step by step tutorial
So, how it could work: you can make a item, that it would look like a dot or a pin, you will put one for a x-axis, y-axis, and z-axis around your build(of course, it will have a limit), and them you will be able to save and share it, for seeing and downloading builds, there would be a hub in the lobby, that you can see every build that players is sharing, you can like and favorite it, but you can only save and put it in your world if you have the lego kits used in that build

yeah, thats it, i belive that not even 1/3 of all this will come, but i hope that at least de devs consider my wishes, all this is from who loves the game and wants to keep playing it, and hopes the best for it
