Because i just watched the intro in Japanese, with English subtitles, and there is like no lip sync at all.

I wanna play in Japanese because yo, this is some fucking anime shit, but this is weirding me out.

Play it in English first. Namely because you won't really be having time to read a lot of the intercom messages when you're in a firefight and also because, yeah, the game was made with English VAs in mind. 
 
Hit up Japanese for your second run.

Too late. I stuck with Japanese for now; not going to change in the middle of the playthrough.

But you're right about that. There's too much shit going on to read most of the in-game messages.

Side note: I really like this game a lot. :)

Baka gaijin! XD moshi moshi Bib desu T_T uguuuuuuuuuuu~~~~~~

English all the way!  
 
...Too late.  
 
But they're American! Why would you want to hear Japanese voices coming out of Americans, who would realistically be speaking American (er, English). 

The English VO is pretty good in this game.

'coz i think it fits the balls-out crazy style of the game better, and makes it feel even more like sci-fi anime to me. That probably sounds dumb, i know.

Also, it was made in Japan. And i usually go for the original voice acting. Only after playing some more did it become obvious that it was made with English voices in mind.

Ah, whatever. I'm really enjoying the game so far. I think i've been wanting a game like this for a long time.

I always go with a language I can understand.

Spanish all the way.  It has a urgency to it.

Steve Blum is the Samuel jackson of VO`s. Why wouldn`t you listen to himÉ

dude play it with dutch VO! amazing

I like to change it up between missions. The french Sam sounds like a proper lethario, where as the japanese one sound completely mental and the English one just sounds like a dick!
