What is to expect form a playing a roleplaying character?

In the pass, I have been playing a game called, Neverwinter Nights rather a lot.

From such game playing online, I usually choose to play on what they would called a “role-playing” server, where players are to role-play, act, or pretend their actions are relatively “realistic” to the environment, and their responds to the people goes the same.

I like to ask, if I was to play a role-playing character, aka a PvE character, would I be expected to act like that I have been on NWN?

GuildWars really isn't much of a 'role playing' game.
You will not find many people willing to role play with you, or act out any part.

You can of course go out on adventures in groups, and have all sorts of fun, but its hardly 'role play'.

Fair enough. I expected such.

I ordered the game and should come this week.

But there are still these small "events" going on in some of the cities now and then where people do something weird or "roleplay" and many people tag along for fun.
