Yeah...because Bethesda is soooo poor. Seems they already had to cut costs in the quality control area. This is such a [censored] excuse. I'm pretty sure they could afford to pay voice actors for the extra lines, especially considering the talent (or lack thereof) of many of them.
They could just have cut children from the game entirely, and also the skill related dialogue.
I snuck very little with my Dunmer character - a glitch caused me to level up sneak even when I was walking normally. Result: Sneak 35, Conjuration 50, One Handed 70, Destruction 70, Light Armor: 50.
And every damn guard comments on me being a sneak thief, when I haven't stolen anything at all with that character!
Stoooooopid.
