It's funny because the moment I got it and was gushing at one of my friends about it I made sure to mention at the end ".. I guarantee it's an out-of-house production, though. Bethesda never does this." I guess my hunch was right, heh. I'm just going to assume Bethesda forced awful voice actors on them then.
I didnt know Arx was made by these guys, though. I love this game even more now. Arx was simply incredible and probably one of my favorite modern [yes, I know my definition of modern is different] games, and Dark Messiah was noteworthy of itself, I suggest both of those games to any fans of RPGs wholeheartedly. I actually know why I've felt such deva-vu in this game, because their other games were similar in terms of choice of Stealth V Combat. It feels like Dishonored is those games but trimmed down and made a bit more accessible to people who don't want to cast magic via drawing runes [Arx] or sneaking along ledges for hours to avoid some fights [DM]. I applaud the effort and if the studio stays around I think their next product will be incredible. Though I wouldn't mind if they made it more complex, a la Arx Fatalis. That game should have had a major impact on what we consider norms in first-person RPG games, especially magic.
