You mean you could actually enjoy MZ to begin with? I couldn't get anything out of it but frustration.
Still haven't played OWB so no comments on that one (although reading about it in one NMA discussion, which I think you took part in too unless I'm mistaken, made me quite interested - so maybe I will fire it up when I have time next).
I actually could enjoy MZ, I found the characters interesting and the environment refreshing.
OWB on the other hand just felt like more of the same, only worse in every aspect and crammed full of "for teh lulz" humor.
So MZ, I played twice, I actually feel the urge to play it again.
But OWB? After the unbearable long intro dialogue when I got out to Big Empty I was like "... That it?"
It's like a crappy version of the Capital Wasteland, sprinkled with random crap and a dark blue tint instead of a greent tint.
I couldn't wait to get out of there.
And that was not an hour in, that was not half an hour in, that was 10 minutes in.
After 10 minutes I felt such disgust that I couldn't wait to just get the DLC over with.
Another issue I have with it is this: It's a sandbox DLC which you 'cannot leave until it's finished'.
So since I just started up FNV for this DLC I felt forced to explore the entire [censored] thing since I payed money for it.
And what I absolutely hate is a sandbox where I can't do what I want whenever I want to.
If I get bored of exploring the north-eastern part of New Vegas I can just fast travel to Legion to do quests for them or go wipe out an NCR camp.
But in Big Empty I couldn't. I was stuck in there until I completed it.
So couple that constant thought with constant repetitive annoying radio pvssyr, with constant bullet sponge robots, Lobotomites and Night Stalker, with constant [censored] dark blue tint to everything and it becomes a naceous experience.
At least for me it did.
The idea that Fallout fans actually enjoyed it or that they think it's even remotely Fallout related baffles me.
If this had been Bethesda's work then a crapload of people would have hated on it.
Anyway, I'm getting off track, I could enjoy MZ a lot, despite it's bullet sponges and linear corridors I found the story intruiging. (I know, shocking!)
I wanted to learn more about the characters and more about this alien culture and technology and wanted to explore more.
In Old World Blues?
I didn't care for anything other than getting the [censored] out, but since I payed for the damn DLC I felt like I "had to" experience it.
So I wandered the frustrating Big Empty for hours "trying" to find something enjoyable.
And then I finally thought "[censored] this, I'm not going to explore the rest of the area, I'm not gonna find the rest of the stuff for The Sink, I'm not gonna fight another damn robot-scorpion" and I just rushed through the DLC main quest so I could get the whole ordeal over with.
What shocked me is not that it's such a horrible DLC, but that it was designed by freaking Obsidian out of all people.
Some say that it's a very serious and intruiging DLC if you look beyond the humor at the serious dark history underneath.
And I'm sure OWB becomes a lot better if you can filter out the ridiculous crap and tedious enemies, but I couldn't, every time I tried to look at Big Empty as a serious horribly cruel experiment playground a [censored]-joke could be heard over the radio...
[edit]
*sigh*
I can't freaking write about OWB without resorting to ranting...
