Yep since mekix going to do the narrative of RPG i am going to do something on character building
first we look at the common stating , STR, SPD, INT, DUR
STR(e.g Strength stat): right so this is your basic capability to do harm, this mean in RPG unless your ability/weapon/whateverthehell says otherwise you wouldn't be able to harm people with a higher level of Durability (DUR) compared to your STR, this is one of the stat that can be forgone in some build, if you want to play the average mage, you obviously won't have too much of this, because otherwise, you would just be a warrior who can do magic durrr, so is playing a scientist, rogue, etc etc . Do describe your STR effect accordingly, if you say "I hit with maximum power" and you are a planet busting by STR give effect to the surrounding of the area like say a crater or two, also responds accordingly, if you have high STR your blow will have great effect, and you should probably take advantage of this , doing it at great detail
SPD(e.g the Speed): the all loved stat, by people who want no harm to come to their character , what is else easier than to avoid all of your opponent attack, sadly no one will want to play with you if you just keep on dodging, there's this thing called "dramatic hit" it's where you got hit by a person with lower SPD, by way of trap or projectile, describe your speed accordingly, "he moves as fast as a blur toward the enemy" is always higher than " he ran toward the enemy, striding his steps" important for rogue and the like, have a clear distinction of your speed, it's easier to respond to " he moved faster than the bullets fired at him", rather than " he moved quickly at extreme speed" WTF is Extreme speed? where is it? how fast it is?
INT ( Intelligence) : the other loved stat, why? Isn't it simpler to rip people head off? versatility is key , with INT you can make things, things that make you have the Stat like all of the above, but there's a drawback as well, choosing to have high level int can be quite hard to convince to people, you have to prove that your intelligence, by planning, by inventions and explaining them (not just LOL i have invented this out of nowhere) by being able to describe the invention in details and of course knowing crapload of things, as a result INT is the one stat that is harder to play , of course you cannot say anything of being a "genius" or "highly skilled in logic" if you can't exactly prove it
being " Genius at the field of choice" is better and easier to be played.
DUR (Durability): be careful when doing this , surviving something over and over again when it is designed to hurt you , is called godmodding, a no no, standing back up when you are hurted is commonly a yes , but do it enough the norm and it is the above again, being hurt could add depth to your RP, as it add sense to your character, not being another wall, if you invest on Regen, you could always write on the process that you are regenerating , growing arms back is better and cooler than walking unscathed from everything ,if a blow is outside of your durability range, there shall be no question, you can't just tank the blow, this much should be obvious.
note: you don't have to jack everything to the max, although it helps if you are playing a real god/demon thing
also taking a ship cannon to the face, and being fine but dying because someone cut your head then burn your body ala twilight is not a good way to tell how Durable you are, you can't have weakness ala superman having a kryptonite, but don't just say "If someone stab me in the heart and the burn my corpse, i will die" when you can tank that universe busting blow to the body
