Firstly lets welcome our newest affiliate Apoqsi to the vault! I've been following his videos for several weeks and really enjoying them!
His most recent video discusses something that was a major downfall in the previous game. To do well in combat the player was very reliant on VATS, especially when dealing with multiple fast moving opponents.
In Fallout 4 there is definitely evidence that VATS is still very powerful but it won't dominate your playstyle as it did previously, a lot of effort has gone into ensuring that running and gunning feels organic and enjoyable and this is great news for Fallout fans...
Be sure to check out some of Apoqsi's other videos and hopefully he'll make an acc here soon (unless he has already and I missed it).
That'd really add some flavor to gameplay. They only tried that once, as far as I know, in FO3, Operation Anchorage, where there was a "sniper alley" of sorts that had four Dragoons in Stealth Armor with sniper rifles. They could wreck you if you were alone, or unawares, but once you knew where they were, they could be picked off almost individually.
