When you decide to roleplay, a whole new world of imagination opens up to you — soon you realize that all the World of Warcraft is a stage, and all the orcs and humans merely players.
There are degrees to roleplaying. Some people like it "light," so that it never gets too intense, you never have to actually "work" to make your character profound or lore-worthy, and it's generally just a fun way to pass some time. Others like it "heavy;" they view their characters as works of art, taking special care to make their characters believable and interesting, and sometimes planning special roleplaying events for their guild to enjoy. Some even try to do everything in-character, from repairing armor to marking out targets with raid symbols.
Recently I joined just such a full-immersion roleplaying guild, and have been trying out their particular style. To be fair, I still have a number of friends on my server that I usually speak out-of-character with, because that's what we're used to, but for everyone in this guild, I do my best to stay in character at all times, with everything my character says and does. To some this may seem like an unnecessary pain, but to others it's a fun experience. Here are a few of the advantages and disadvantages of this type of roleplaying.
