Tedious to set up is something you have to get used to if you're going with C++
SFML is fairly straightforward though, just follow the tutorial and you'll be fine.
Ok so I know it's been asked a thousand times, but what language truly should be used to make good quality games.
Out of curiosity, why do you think you'll get The One True Answer if it's never been given before in the thousands of times this question has been asked?
>>You can use any and there isn't a specific onelockquote>
And you just answered your own question.
>but based on the fact that I know a small-medium amount in C#(XNA framework), C++(just basic stuff), and Python(a little more than I know about C++)...which should I try to learn the most in right now for developing an independent, most likely 2D, game?
Any of them. Seriously, you're very likely (as in 100% likely if you actually have any interest in programming) to learn several languages as you go through life making games. Using one now doesn't prevent you from using a different one later. Just pick whichever one you enjoy working in the most. And if there isn't one that stands out as particularly interesting or enjoyable to you, put them on a dart board and throw darts until you hit one. Seriously.
Im going with C++, any suggestions on libraries for a 2D game, I will eventually start 3D so I was thinking SFML but it seems so tedious to set up.
