Roleplaying is very important aspect of fun - its what gives feeling of reality and makes the gaming experience deeper.

As a DM, I try to encourage players to emote and roleplay, but not force them to it. I also try to avoid limiting their creativity as much as possible.

As a player, I focus on my character and roleplay him. I try to avoid going into out of character discussions. But it's not always possible. There are situations where some careful OOC contact is necessary.

I've participated in various forms of roleplaying - from classic tabletop to LARPs (over ten years) and online NWN games - both persistent worlds and games with friends (over one year of experience).
