After seeing Twin Matrix's post I felt I needed to address it fully.
I'm sick of seeing these generic names and story plots on all of these RPGs, they look like they're all made by 12 year olds. So I'll list a few things that you should probably stay away from.
Dragons in general, unless your game is centered around them, or a normal fantasy game.
Names from any Final Fantasy, which means no towns or provinces named Firion or Tidus
The name Leon. Seriously.
The idea of a "Chosen one" because it's done to death.
Nothing where say, a 16 year old kid, with modest upbringings rose to become a hero due to some unforeseen event, it sounds like a bad B-movie.
NO circumstance where your characters village is burned to the ground by bandits or something.
Compulsories of dark dungeons, fire caves, wind temples, ancient ruins filled with traps.
And another thing, the "Cloud rule" which means, the crazier and bigger the hair of the main character is, the more important he is.
Hilariously stupid and clueless soldiers.
No matter how big the sword on your back is, you never stand out in the crowd, seriously, why does no one ask why someone bursts through the door while a family's eating or something?
The Aeris effect, which means the main male character has a BIG ASS sword, and the female has a rod/staff
SLEEP CURES EVERYTHING. even death.
Every country in the world will have exactly one town in it, except for the country you start out in, which will have three.
No giant robots fighting. (which is ironic though, as I'm making a Front mission fangame)
The ancient evil rule, which is when an ancient entity arises from it's tomb to wreak havoc and a group of heroes have to seal him away.
The predatory species of the world will include representatives of all of the following: giant spiders, giant scorpions, giant snakes, giant beetles, wolves, squid, fish that float in midair, gargoyles, golems, carnivorous plants, chimeras, griffons, cockatrices, hydras, minotaurs, burrowing things with big claws, things that can paralyse you, things that can put you to sleep, things that can petrify you, at least twenty different creatures with poisonous tentacles, and dragons. Always dragons.
At some point, you're going to have to talk to a tree and do what it says.
And why didn't they use a phoenix down on Aeris?
The Moral Of The Story (Ghaleon Rule)
Every problem in the universe can be solved by finding the right long-haired prettyboy and beating the crap out of him.
I hope you find this useful, I found the list at this site right here
I didn't make this. I agree with a few points on this though.
