the witcher didnt sell that many copies really, 1.2 mil is not that high a number....and they sold it 3 times so you would have to count each box separately (normal/ce+enhanced) which they didnt. 1 mil plus is kinda a good number....but not when you re-release a game a year later with nominal added content.
launching europe exclusive is kind of a suicide move really, especially when you consider translating to the europe languages means you already translated to all american (north and south) languages anyways, better to just go global.
but i digress, i must get back to that tower so i can get all that storage going on.
Where are you getting those assumptions?
CD Projekt Red made themselves a force to be reckoned with, with the Witcher. Any title that sells over one million copies, from a company as small as that one, is definitely a huge blockbuster. I'm sure Larian would be happy with a number like that. I dont know any figures on DivDiv, but I'm sure that was Larian's biggest success so far, and also first released in germany.
If you're talking Oblivion or NWN2, you're talking major backing and major developer... for a smaller developer, figures like theirs are nigh impossible to attain. The original NWN got to maybe 3 million? from a game that boasted such innovation and possibilities, got such fantastic reviews, and was made by the biggest RPG developer out there... After 6 years and loads of premium mods and expansions, they were up to 3 million.
And I am thinking the reason they released first in Europe is not because the English dialogue isn't ready yet. I've read that Divine Divinity was finished in English, translated to German and released first in Germany. So that's not really the problem.
