I mostly collect Collectible Minifigures and Nexo Knights, though I do also have some 3-in-1 Creator sets and I'm hoping I can dabble in some themes from around 2009 as well!
On the television side of things, I personally love Nexo Knights (despite its shortcomings) - it's what got me into collecting smaller sets for that theme, so marketing ploy accomplished! I also enjoy Monkie Kid on the side, and I might look into DreamZzz as well!
