charisma snd speech are both useless, utterly useless.
so is sneak.
While I don't disagree that Charisma/Speech are some of the least usefull skills overall, how is sneak useless?
I spent 85% of my time in Fallout 3 sneaking to scout and strategize where needed. It creates its own unique playstyle that I find more refreshing than running around spraying everything.
Let's not forget about an automatic critical hit from sneak, assistance with theft/pickpocketing, or the pure strategic value of being able to sneak. Also being able to dispatch multiple enemies before any find your location thanks to sneak.
Sneak is not as useful if you prefer run n gun, but certainly does not make it "utterly useless" and this game can be played just as stealthily as it can be hastily.
