I'm not exactly over the moon with the way that Steam handled Fallout: NV pre-loading. I've never pre-loaded before so maybe it's always this way. In essence, once the game unlocked I tried to run it only to find it needed defragging. Fair enough. Got that done and then Steam decides it needs to download a further 2 gigs before I can fire up the game. I really wanted to test it before I left for work this morning but that put the kaibosh on things
Ah well, still quicker than heading to a shop I guess.
