I thought the Killzone 3 Demo in Japanese was an interesting thing to share– it sounds really different with Japanese voice acting. Or rather, it sounds really over-the-top when they do sound effects. You know the “UAAAAARRRGGGH” sound effect. It’s really funny because that’s also the same case with some English voice-overs for Japanese games.
I actually really like the Japanese voice-acting though! There’s also a Russian and a German option.
