I try to put in as much colour as I can in my characters, but I do not let my alignment or other character traits cause conflict within the party. I want everybody to have a good time, so if I'm playing a D&D-style Lawful Good priest, I will talk like a preacher and do things in accordance with my alignment, but I won't squabble with my Chaotic or Evil teammates, unless we all agree upon it.
I like to try and make my character be a unique influence on the story or gameworld - I really enjoy the narratives we create during a roleplaying session and I'm willing to cooperate with others to fulfil their stories, whether they're GMs or other players.
I can sometimes be the "take charge" type in group play, but I'm perfectly willing to tone it down if asked.
As an inveterate gambler, I also like to roll them bones every once in a while.
Just like I do as a player, I enjoy the narratives created during a roleplaying session and as a GM I want to help characters create their own stories, whether they are giant character epics or personal, down-to-earth miniarcs.
As to how much I use dice and rules during the game: that depends on the players. I used to play MERP, Rolemaster and FUDGE, so I'm comfortable running both crunchy and smooth games.
I speak native English and Polish. I can also manage playing (though not GMing) in Spanish.
I live in Spain, so you should probably keep in mind I'm in the UTC+1 timezone.
I work irregular hours, but I am generally available any time on Fridays, Saturdays and Sundays. I may sometimes also have free evenings throughout the week.
