The latest trailer for Platinum Games's latest, Infinite Space, features some brief clips of the shipbuilding and space combat elements of the RPG's gameplay. It also features voice acting. Yes, those are human voices speaking lines of dialogue from the game. We don't want to make any judgments about the quality of the voice acting, but we can confirm that it is, in fact, voice acting.
On an unrelated topic, we'd like to talk about the Nintendo DS's volume slider (and the DSi's rocker switch). Isn't it great how the volume can go all the way down? Why, with the volume minimized, you could enjoy all kinds of interesting games, even if there's some kind of audio issue!
