The efficiency depends on the query size relative to the data distribution. A small query in a sparse region prunes almost everything. A query that covers the whole space prunes nothing (because every node overlaps), degenerating to a brute-force scan. The quadtree gives you the most benefit when your queries are spatially local, which is exactly the common case for map applications, game physics, and spatial databases.
There are three main sets in the launch, based on some of the most iconic, fan-favorite creatures from Pokémon's 30-year history. Those include Pikachu, of course, as well as Eevee, Charizard, Venusaur, and Blastoise, all recreated in Lego brick form. Pokémon fans young and old can continue their trainer journey and catch (build?) them all brick by brick.
