This one doesn't do it for me, sadly. I find the quests repetitive and the Big MT bland to explore. There's a lot of funny (your mileage may vary) dialogue but the whole thing is hellishly goofy to a point that I consider it a disservice to the base game's tone. I tend not to include Old World Blues in my playthroughs unless I'm gagging for the +2 STR you get for having your spine replaced.
