Funny, I saw you reply to two of my posts in topics that have been silent for a pretty long time. Ayway, I'll refrain from quoting and explaining myself, so I'll just tell you to read the 'used vs. overused' part again and draw your own conclusions.
As for unique; It's best to believe unique ideas no longer exist in this world. Non-existent or just way too fucking hard to pull off. There is so much literature in the world, in many different languages, published works but also unpublished, like pretty much everything on this forum. Sure, there is a slim chance you may think of something nobody ever did before, but that's like one in a near endless number.
"My mother and Father dissapeared when I was little." NONONO
But what if you ATE your parents before you gained conciousness (the first years of your life)! Well, I guess this is a combination of 'parents missing' and 'amnesia', but just to give an example. Clichés work, they are used to develop the character in a certain kind of way. It's just poorly executed most of the time and thus it gained a negative image.
Weapons- Try making your own, or such.
NO! Why not? Very simple; you need a practical weapon. Creating a new weapon that is practical requires a lot of thought. What technology is available in that world for example? In the European medieval times they couldn't make thin flexible blades for example, so a 'dancing sword' is a no-go. What weapons are in use? If you create a kind of sword in a futuristic setting ... Well let's put it like this;
"OH NOES LOOK OUT IT'S A RAY GUN!" Pyew, pyew! "WHERE'S YOUR LIGHT SABER NOW BITCH?" You'll be killed before you even come close, it's not practical to draw a sword in a gunfight. I'm not even talking about balancing the weight, control and ability to carry the weapon around...
It requires a lot of thought and research to create a good, practical weapon and most people just can't pull it off. It's nice to have a seven-section staff, but how the hell are you going to use all seven sections properly? Better stick with the usable three-sectioned version, or a nunchuka.
Age-dont be 19 18 20 everydamn time!
To write a middle-aged person is very hard for someone who's in his or her 20's, or even still in puberty. And face it, the majority of the site is in that age category. Most people can't pull off a believable war veteran if they're in high school, no matter how empathic they may be.
Personality- Dont always be Naive and run out in the middle of the battle field. And this gets worse when more than 1 person in the rp is this way.
Yeah... This is the part where you secretly PM the GM if he/she would please consider killing off mentioned naive character...
