I generally like voices: I suppose for me it's not so much the difference between watching telly or reading a book, but watching a silent movie or a "talkie". Older isn't always better.
Voice acting can make or break a game, so it's a gamble: I'd love the sort of voice acting we had in Ego Draconis, but Beyond Divinity less so. And yeah, it is expensive, but to me it just feels unfinished without it.
