To play Diablo 3, you have to choose a BattleTag. Blizzard says the name will represent me on battle.net. I already have an account name for Starcraft 2, and I'm wondering if I should use the same name for the BattleTag.
On the one hand, I'd would be nice to have the same name for all 'accounts', and also Blizzard might move to the BattleTag for Starcraft 2 one day. On the other hand, my Starcraft 2 name is rather sci-fi themed, and I think that would be weird / bad for the atmosphere in Diablo.
I'm wondering: How is the BattleTag is displayed in Diablo? Are there also character names, and what is more prominent?
(And the following is a soft question and not really fitting for the site, but I'd still appreciate a comment, or an addition to your answer: What do the BattleTags tend to be like on average? I mean more thematic like, dunno, 'VigorTheConqueror' or 'DemonSlayer', or are there a lot of silly or off-topic names like 'Tassadar' or 'TupacLives'? ;-) I don't want to pick something that sticks out like a sore thumb. I'm probably overthinking this, but maybe someone could add their opinion.)
