Nope, the base game is pretty much everything you need

Black Market Aerial Pack just for the Dual Parachute Thrusters

The vehicles are worth it for screwing around, anything else is pretty much just a matter of choice.

I liked the Assault Rifle though.

hmm thanks for your opinions

There are better mods out there, so ignore the DLC.

The multiplayer is what will make the game worth 10 skyrims, thats the biggest posibility.

TRUCKSTRUCKSTRUCKS.

But seriously, the jetpack one is super fun.

Multi locking rocket launcher is nice =D

Get the black market boom pack so you can do this :P. http://www.youtube.com/watch?v=ECtk4WxrYxI

just the base game is enough

Iv decided to get all the dlc except the rifle one :)
