I found them quite entertaining to read, but why would you not use VO for them? I mean, the voice acting in this game is SO good that having them speak to you would have resulted in much more absorbment into the world. I don't believe it's anything to do with budget, because tons of games have ridiculously more voice work, so as I said it just strikes me as lazy.
The posts are about the audio levels are completely true, also - I had to turn subtitles on just to be able to understand what was going on, because if you were shooting as a message popped up it is impossible to hear what they were saying. Especially annoying on the audio log collecting quests.
Everything eles about the game I love - I just appreciate a good story in games, too, and that's where Borderlands is below average. Well below.
