Right just got ultimate edition got the packs but i need some info started old world blues right or wrong?

You can never go wrong. Although, I would say that a stealthy, energy weapon specialist would have the advantage here.

Right or wrong what? Meaning if you should play Old World Blues DLC first? I usually start out with Honest Hearts.

Also, there was just a recent thread that stealth doesn't really work well in OWB. I stick to higher ground when I sneak around in OWB, use the pipes and bring a modded sniper rifle with you!

Right. Someone stated that even with sneak at 70, pip boy light in the off position and the associated perks such as quiet running, they were still being attacked by some creatures. There was also a rebuttal in that those specific creatures were scripted to attack the player no matter the conditions.

If it's your first time with the DLC's, I recommend playing them in the order they came out:

Dead Money-Honest Hearts-Old World Blues-Lonesome Road

I actually still prefer that order, I just love seeing where some of the characters came from after meeting them.

get to level 12 at lesst then hit the DLCs you can have a bad run through if your skills are not incresed to a good point

Im with that guy. and I wouold definitley reccomend playing them in order.
Oh and when you start Dead Money remember to take it slow and dont skip through the dialoge, its (imo) the best the game has to offer. The ending slides still give me goosebumps just thinking abut it.
