Russian all the way! No language sounds more badass and sexy in a strong way than Russian.

Spanish!!! That way, you'll finally learn to read my username and understand what it means.

Edit: Also, why is Spanish the only option in your poll without capital letters? Stop the racism!!  

In a couple days... whats your username there? Do you visit the Vita thread?

Cool I grew up with English & Marathi. Learnt Hindi through bollywood. The language your write with basically the same for Marath & Hindi.

Wow Japanese was the easiest was it...that's very interesting. I have a good affinity for anime...a very good affinity BUT I won't have time to see a lot of it. So in regards to Japanese what level would you say you're at in terms of reading & writing?

OMG that is insaaaane!!!

@Morenoin

LOL that is bothering me so much. Not because of racism but because of my OCD of needing to have everything ordered similarly or symmetrical.

@Turkish

Ironically I am called TheEmperor on Neogaf LOL 

Sprichst du Deutsch Ryan?

I guess German can be handy if you plan to attend Octoberfest or Gamescom :P or even Rock am Ring / Rock im Park.

J/k aside. Learn the lanuage that you intend to use. Either you have friends with whom you can use it or you intend to travel, relocate, work in a country where that language is spoken. There's honestly no point in investing your time into something you won't use. Language is not like riding a bike, you have to nurture it, train it... Or you'll simply forget it.

Reported for not spelling Oktoberfest properly.

If you won't have time to immerse yourself in anime, then maybe it won't work as well. When I started Japanese, I was basically watching ~15 anime episodes a day (it was summer) so I picked up a lot of stuff. Spoken Japanese really isn't hard. Honestly, right now, I can watch anime and understand ~70% of it already. I can also communicate most basic messages and some slightly complex stuff. The sentence structure is very easy to pick up and it has only a few exceptions for most things in grammar, unlike English, in which there are exceptions to exceptions to exceptions. I'm not joking. There's nothing along the lines of the thousands of exceptions in English to i before e except after c or when sounding like a.

Reading and writing, though is where it gets painful. Japanese basically has two scripts; kana and kanji. The kana are divided into two sets of alphabets that have the same pronounciation; one for when they're using foreign words (like "power", which becomes "pawaa" and juice, which becomes "jyuusu"), called katakana and one for normal Japanese words, called hiragana. There's a little less than 50 different letters that you have to learn to write in both types. This might sound a little confusing, but this much you can completely master within a couple of months at most, I bet, because the pronounciations are horribly simple. Altogether, the Japanese language only has about 120 sounds you have to make. This is compared to some 30,000 we've learned to make in English, apparently. (And who knows how many in Hindi!)

The kanji, however, are basically fairly complicated Chinese letters similar to hieroglyphs in their function. They represent ideas and not pronounciations in themselves so they usually have lots of sounds for each character. Worse still, there's 2000 of them to master if you want a basic level of literacy (most Japanese adults know over 5000 if they read a lot). I'm only at about 200 so far so reading books is outright impossible. Video games are a little easier, but not that much. Meaning my reading level is comparable to a seven-year-old Japanese child at best. My writing is even worse. So if you pick Japanese, don't expect to be able to play video games anytime soon, though talking to Japanese people shouldn't take long at all.

Sorry if I went on something of an unnecessary ramble about Japanese there. Hey, at least you're more informed now, :P.

Imo you should pick one that is both practical and asthetic to you, so it should have some possible use given your circumstances/career and you must simply like hearing and speaking it. Two big emerging markets are China and Brazil, so Mandarin and Portuguese are obvious choices. I've been told that Mandarin has a fairly simple grammar compared to English or German, so I'd favor that one over Portuguese. Other quite practical languages would be French, German, Spanish and Japanese. I wouldn't bother with the rest tbh, since you would have to madly adore them in order to consider those over the more global ones, and if you did then you wouldn't have needed to post this thread. ;)

Which language do you consider the most beautiful sounding?

Me personally i would pick Japanese, Mandarin, or Russian. It also depends on which country you live in and if there is a demand for people who speak another language like here in the USA there is a demand for people who can speak spanish and english, or are you learning to just know or do something new?
