Regulus Tera said:To stop importers. That way they have to wait until the game gets localised and the sales numbers don't get skewed towards one region or another.
It's not so much that (because, really, import sales of games are largely negligible at best, and just count as sales from other Regions like Hong Kong), so much that they just want to do more to cover their own ass, legally.
When they state in the opening of the games how "This game is meant to be played in [insert region/country here] only"? They mean what they say. If you choose to import, you're basically operating outside of your "legal jurisdiction" (so to speak), and therefore, you're on your own. Anything good or bad that may happen will then simply be on you.
