D3 is briliant as a game. However,it does have some problems with the online requirements. Not everyone in the world who owns a PC has cosntant internet at usable prices. And it doesn't say in the box about the constant online conection required. It doesn't matter how many time Blizzard stated it in press conferences or in online sites. There are people who don't see those things and don't live an intense online activity to have heard about it. The box of the product needs to state exactly what you need to be able yo play, obviously.
@TigusVidiks While I agree that people have been more harsh than nessesary about D3, I do not think it is "brilliant" by any measure. It's a good game, but from a developer/publisher like Blizzard, it falls far way below the mark. After many months of patches, it's still not a rewarding experience after finishing inferno.
