Could be anything from a concept you gravitate towards often or maybe a trope you make use of more than you like.
For myself, I often find myself making way too many wandering adventurer groups, often treasure hunters. I find em really fun to make but I also have a lot of them.
The whole background premise of my world (although it doesn’t come up that much because it happened long in the past) is humans going to Alpha Centauri and then for unstated reasons end up cut off from Earth and kind of have to start anew which I think is quite cliché, but I don’t really care because it’s just an excuse to do my worldbuilding with humans but without the weight of human history on Earth.
Is this cliche? I can only think of Lost In Space but that’s quite a bit different
