Dynamite in the game as a weapon is useless.

To qualify this statements here are some observations from the game:

• Dynamite is so underpowered its a joke, thats perhaps not a bug just my opinion, but an enemy has to literally STEP on the sticks when they go boom to cause more than about 5% damage
  
• Without VATS dynamite will bounce so randomly as to go practically anwhere inside a large area, and because its so underpowered it is therefore useless without VATS.
  
• When you use VATS to dynamite a creature, it slows only THAT creature down.
  
• So if fighting a pack of ghouls the rest will still come at you as quick as ever, despite the targeted ghoul being in "bullet time".

Given all the above, dynamite is useless!

It is a weak weapon on its own. You can use dynamite in crafting recipes though for much bigger explosives and you can find a bit more Dynamite than any other kinds of explosives. I mean, through 3 starts I've found over 50 sticks in each before ever leaving Goodsprings.

I agree with Lizard, I look at them like noob grenades. Grenades seem to be more hard to find here than dynamite so it's like a make due thing. I did find a crashed semi with just under 20 grenades inside though close to that starter town So I'm really happy now

Well i dont go in for that crafting cr*p i'm still trying to figure out why i seem to clone a copy of every bullet case that i can see is falling to the ground. Thank god they are weightless or i'd be quite upset! It is still a bug though as the game is meant to go into slow motion, not just the targeted enemy.
