From what I've seen, Fallout 3 does not have any of the qualities of the previous episodes. But that was to be expected. However, it has none of the diffuse magic of the Elder Scrolls series. It feels like Bethesda made a break with this new title, a sad bend towards products multiplying "fan service", the dumb, goofy stuff that will make the client laugh, the "awsum roxxorz" elements and micro-gameplay to the detriment of world coherence and deeper mechanisms. To sum it all up, expect loads of shallow combat spoiled by VATS and slowmotion sequences as gore as pathetic, a terribly short main quest - a Spanish colleague has finished it in less than an afternoon, during his first playthrough - nice secondary quests, but which completely missed the intelligence and density of the series, the whole being flavored with failed occasions.

VATS slow motion may be the worst crime against video gaming since the invention of the auto-aim and checkpoint based save system.
I don't know what the people of Bethesda had in mind... Maybe they feared that the game would be too short and imposed a twenty seconds on us at each targeted shot to extend the gameplay length, maybe they really desire that we notice their face modeling with independent eye globes, maybe they simply suffer from blaring bad taste, from a love for Brotherhood of Steel they want to share at any price?

Either way, this "feature" that retarded teenagers and moronic fans of "self-confident but still crappy" violence will love (and even then, not beyond the 10 first minutes), guarantees that you will avoid using the targeted shot system at any price. It sucks, it's ugly, it's not funny, it's long et absolutely useless.
Worst of all, there's no way to skip it or deactivate it in the options. You will be then forced to endure these scenes not even worthy of Soldier of Fortune 3.​
