Until the past few years, I did exclusive science fiction roleplaying, but I abandoned the genre when it became increasingly obsessive over being science fiction. It became ever more a chore to explain details of characters, stories, locations, abilities, among others, to the point the community I was aware of was moving steadily and deeply into the "Basically science and fact, just not there yet." genre of science fiction. I had eschewed and scorned fantasy because, contrarily, nothing meant anything to the majority of players in that other side of the community and none had ever established any consistency to how or why things did, as well as typically having less quality players, more often because they were young or worse were powergaming.
No less, that transition period came just as supernatural and fantasy media again became massively mainstream and popular among the younger teenage demographic and while that particular event left me embittered for a while, it never quite killed me interest in writing and formulating things I considered "better". Ultimately all it did was force myself to create works that skirted what I saw as flaws or failures and inspire me to improve. Sadly, most my former compatriots chose to fold or tuck themselves into their niches.
