Oh my. Re-reading one's oldest posts never fails to be quite a "cringeworthy" experience, however, this one is much too amusingly awful to pay it no mind. Let's dissect this atrocity for a moment:
Score? Since when were video game soundtracks "scores"?
Tsk tsk. "Successful" contains three S's. And is this studio's supposed success the only confounded reason you want a job there? Do you even know anything about them?
That's a bit of a redundant statement.
The best part of what, precisely? And how would this ever be impossible?
I believe the term you're searching for is "apply for a job".
What other platforms would a fangame be developed for...?
...Alright, alright, I'm finished nitpicking. Heh. Anywho, I may as well make this post relevant to the topic at hand, thus, I'll restate what my "dream job" would be:
A composer. Ideally and more specifically, a freelance composer, but I won't kid myself; it's quite a pipe dream. Otherwise, I would happily settle for a simpler variation on the occupation, be it a video game composer or another similar alternative, but only if I retained full artistic control. None of that executive meddling nonsense.
Suppose my quintessential career choice never comes to fruition, I would certainly be content as a writer or, once/if it becomes a valid market again, hand-drawn animator. Anything artsy will do, so long as my creative freedom is completely unleashed and unrestrained.
