I dont really think its that you need to be a good scripter/level maker/gfx maker to be manager. You just need basic knowledge of it. As far as personality goes I think that yeah you should be a nice person. Not too nice but nice. You should be able to handle any situation no matter how hard it is. Also you should stay calm if any of these situations arise. You need to be trustworthy and have a take charge attitude towards things. Although these are traits that a decent manager must have. It doesnt make you the best. To be the best you have to beat the rest.
