我个人决定使用Java进行游戏（现在），因为我非常喜欢Java，而且使用C ++也不那么容易。但你会发现大多数人使用C ++的商业游戏。实际上，我开始与pygame（python游戏框架），这也是很好的开始，特别是如果你知道python。

I personally decided to use Java for games (for now) because I am very comfortable with Java and far less so with C++. But you will find that most people use C++ for commercial games. Actually I started with pygame (python games framework) which is also nice to get started, especially if you know python.
