"Baldur's Gate: subtitle" would have been the ethically proper way to go here
I don't recall any ethics debates over Fallout 3's name, etc. Lots of game / movie / book series have used numbers without being a direct continuation of previous entries.
So, what are you saying then? I'd still argue the same point as Raze. Plenty of franchises have continuations in their title, when the first story is even completely finished. All of this sounds like a personal opinion/expectation, and you want everyone to have the same opinion as you.
It's a '3' because it adds more to that universe, bringing in more stories to the fold. I really don't see why, what or where your upset is coming from.
