I love fantasy and mythology in my game
but I also I think there is sort of yin/yang balance between realism and fantasy
like for realism i really want them to add to relationships, romance, interactions, cultural things, struggles,family and past themed gameplay etc. which all would all make great support for my fantasy
action also goes hand in hand with few things i do like so I am not against that per say i think it makes interesting add
as for scifi I am not that big of a fan in sims because it often comes with machines and I feel we have enough of machines and tech in sims 4 and I'm quite sick of it though i do like me good dystopia cause im evil like that and id also love if they fixed plantsims and aliens
