I think people would say this was a sack of faeces even if it was spectacular, because hardcore game fans are as resistant to change as a 1950s American conservative. Making it an MMO was always going to ruffle a lot of feathers.
Of course it might be shit house anyway. But given that factor, and given that Bethesda are notoriously bad at releasing complete, bug free games, I'll pretty much wait until a few of my mates have it and see how it is then. I'm not really an MMO fan but if it's an enjoyable game the fact it's Fallout will get me over the line...
