As for the amount of travel, if they had been a little bit better about distributing quest givers-think WoW quest hubs-the game would have a bit nicer flow-go to one area, do all the quests, maybe have another quest that takes you to another area, etc. Some map-crossing but nothing too bad.
Though that's definitely something that's sort of a 'oh, that makes sense' post-mortem kind of item. Still, I didn't think the travel was TOO much, mainly because the journey is really the destination most of the time.
as for voice acting, years and years of eastern euro PC games have made me immune to inadequate voiceovers. anything short of "SUFFER LIKE G DID?" does not faze me.
