I play it mostly as an FPS, only use VATs on more difficult opponents/Situations, do very little Crafting mainly just Recycling Ammo. Crafting is only really necessary early on, which ironically is also when your ability to Craft is severely limited, or perhaps if you rush through the Main Storyline. Myself, I explore everywhere, Loot every Desk/File Cabinet/toolbox/Body/etc, do as many Quests as possible, and because of that I have so much stuff that I've got stashes of Mines, Doctor Bags, Weapons, and all kinds of other things at various places and in my Companions. So much stuff that once in awhile when trying to offload more onto a companion I'll find something awesome, like 2 Sniper Rifles for Repairing :awe:.
The game's(3 and NV) are a ton of fun.
