Creativity, imagination and having a good time.
I've done some of that you guys call "super-serious-realistic-leet-only-roleplay" and at start I thought; "Damn, this is so cool! Do everything I do in real life in a game!".
But all of this;
* tiderman digs in to his deep pocket.
* tiderman picks up his brown wallet and opens it.
* tiderman unzips the coin "slot". (pocket w/e)
* tiderman picks out a coin.
* tiderman zips the coin "slot".
* tiderman dusts off the dirty coin.
* tiderman puts the coin into the soda machine.
* tiderman looks at the different kind of sodas that are available.
* tiderman pushes the 7up button.
* tiderman hears the machine scramble.
* tiderman grabs the soda.
* tiderman opens the can.
* tiderman sips on the soda while being awesome.
* tiderman whines about dual weapons and noobs who can't f**king roleplay for shit.
.. made it boring. I guess it's not for me
I like the kind of roleplay that when you turn off the game/computer you do it with a smile on your face thinking "That was fun!". You know?
