(Totally deviating from the topic of Greek and Roman pantheons......)
Here's the biggest style assumption that has never made sense to me as I've experienced it first-hand----
My primary play group is all-in on Savage Worlds as our primary game.
My secondary group, on the other hand, is head-over-heels in love with GURPS.
But to this day I can't figure out their abiding love for it, because without fail they push and push and poke and prod against GURPS' general, built-in playstyle assumptions: "realistic," real-world characters and situations, combat is deadly and to be avoided.
Instead of taking GURPS' general assumptions at face value, they instead do everything in their power to play against them. Anything less than a 300-point starting character is considered "totally gimped" and nigh-unplayable by them (for reference, GURPS 4e suggests 125-150 points qualifies as more-than-competent starting point). They love the detailed, deadly nature of combat, with active and passive defenses......but then force themselves to take every advantage in the book to mitigate that deadliness. "Your character is useless without High Pain Threshold, Combat Reflexes, and a movement score lower than 7. Why would you even bother making a character without them?"
I honestly can't figure out why they're so in love with GURPS, because really, they don't want to play GURPS, they want to play a superheroes game where they're just that much better than everyone else.
Which would also make sense, considering that their 2nd favorite games are all made by White Wolf, which basically are games about undead "superheroes" living in the real world, trying to deal with their own dark morality.
I keep thinking maybe they should just switch to HERO.
