Don't worry about practicality. Just go ham and blow your fantasy.

Mine is something I've been imagining since I was a kid. It'd be called the "Black Box Collector" series.

Essentially, it'd be a 1/72 line of unimaginably detailed scenes, such as cargo ship harbors, construction sites, etc. You could buy dioramas, with a premade landscape and vehicles, or you could buy vehicle packs which would just be a box crammed to the brim with whatever type of vehicles it contained.

Some ideas are like:

Nazi Germany pack: All the tanks, planes, and boats of the wehrmact in 1/72 scale. The box would be fucking huge obviously. Upon opening it, it'd be chock full of everything you can imagine. Unboxed it'd cover an entire floorspace worth of vehicles of every kind.

Construction pack: A smorgasboard of construction vehicles. Be it kubata, john deere, or what, there'd be excavators, loaders, you fucking name it. Cranes, cement trucks, all of it.

Ocean liner pack: The titanic, olympic, britannic, mauretania, lancaster, all the white star line ships from the 10's. Still in 1/72 scale.

It'd just be the wet dream of any model collector. The models would be created by hand. The prices would range from $100-$20000 dollars per pack, due to the sheer amount of shit you get.

It'll never happen, ever, but fucking hell. Little me would've drained his balls before his dick was even hairy.

What about you guys?
