i like c#, there is soo many powerful programs you can make, and you can make emulators of major games with it (me i made a shard (the name for the server emulators) based off of the game of Dark Age of Camelot) i dont make actual programs yet but i like seeing the results of my programming in the game, theres so much you can do
I use C#, C++, Python. These three all togeather will rock your socks. ANd example of my work php,e107,IPB-Protection Hack. I crated this to protect from dossing and It opens all the files chmod to 777 for you if you are under a subdomian free host.
