No in languages you do speak
I see. Well when I started with PC gaming, the first few games I played in German, my mother-language. I started to switch to English though because the voice acting is just better, as it is with most original voice actings.
I still like to compare localizations of games to the originals but now I play everything (also watch most shows) in English, simply because it is the best experience.
Though the german voice actors of L4D2, were really good. I played that game in German for a long time, until Valve realized that the L4D1 characters in L4D2 still speak english. So they patched in the german voices of the first game in, which made me switch to English because the german voice acting in L4D1 is one of the worst you have ever heard in a game.
