Dude, I love stories, writing any stories not just rpgs, and I struggle with that sometimes. there are cliches I hate, even if I like other ones. like in my pokemon fan fic, I'm trying to write a determined hero who uses more than just force to defeat her foes and try to get tricks of guile and tactics in there as well, sometimes I have to let the force happen if I can't come up with anything else so I can move on and go against the cliche in a place thats better and suited when I make it good, because I've found that often if you can't avoid a cliche, its best to just execute it well and with as much thought as possible so that when it happens things play out realistically or believably because of it.
Edit: just realized after I posted this, it sounds like you like rational fiction. its a genre thats most common in sci-fi but is starting to spread through fan fiction. maybe go read some of those? its all about characters acting as smart as they can without any contrived stupidity.
