So, I finished Honest Hearts and enjoyed it. I loved the loot I got at the end and enjoyed the new locations.
Now, I am going to start Old World Blues and would like opinions by people who have finished it.
I am currently at level 28.

What I know so far: it's funny, the setting is interesting and the enemies are bullet sponges.

Thanks for sharing your thoughts.

If you're not using energy weapons you might ignore all the energy weapons and energy ammo lying around, or just sell them. Don't. The energy weapons are pretty effective and there's not a whole lot of ammo around for regular guns (but that may be due to the mods I'm using). Either way, even if you normally don't use energy weapons you'll probably have an easier time by having one or two energy weapons as back up.

Also keep an eye out for holotapes inside buildings. They're everywhere and they'll come in useful.
