I'm Spanish, but that mostly differs from how well the voice acting is. I remember playing the first Metal Gear Solid, and I was impressed on how talented the dub actors where. (Alfonso Vallés FTW).
That being said, whenever I can, I put them in English. It has been a nice way to learn the language and to enjoy a good voice acting. However, there has been exceptions. Metro 2033 and Last Light; I played them in Russian. Alone in The Dark (the newest one) I played it in Spanish, but mainly because the other language's voice acting sucked hard. (Spanish was pretty good!).
And if it's an JRPG, Japanese. However, I couldn't with Resonance of Fate, mainly because the voice acting suuuuckeeeeed sooooo baaaaad. English was pretty solid. And that's strange, considering in most JRPGs, the English version tend to be devoid of any emotion.
