In terms of theology lego does not matter very much and you migjt think why am I mentioning lego all of a sudden well it's because it's a great tool to understand religion from a godly perspective. You see when building a little town or city in lego sometimes you want lore to take place so you build kingdoms and fun places and sometimes even start a religion and even tho you could pick fake lego gods but really usually you will end up making a temple dedicated to you because you created the world and this is were my experiment starts. People with a god complex usually don't like it they can't be all powerfull so they will find other ways to be powerfull or to feel powerfull I (having a little bit of a god complex of sorts but not full scale) have had problems trying to find something that resembles that feeling very well
Some might get good at certain games so they can dominate in those games and others might choose to climb to the top in real life but this isn't always as easy as just going out there and doing it so I personally have found myself to use lego as a way to prevent me from being a self entitled to everyone around me and still maintain the feeling of being a sort of god over something or someone and even tho these figures are plastic toys it still gives a feeling because it's great to look on a world you shaped with of course the plastic little bricks and it makes you understand how it is from a gods perspective because you are still deciding on how your plastic lego figures look at you as a god. Do they know what you look like, how do they think of you are you a fearfull or a kind god and will you punish them for not following your rules
That's really it and this is what I found over a little experiment I have done over a couple of years of course it's more detailed then this but this is basically what I found with enough fantasy lego can help you with god complexity
