疑問：pygame已經過時了嗎？
過沒過時不知道，反正這玩意官方已經快四年沒有更新了。用的人還蠻多的（相對於其他同類項目），不過大家都是用來寫寫小東西玩一玩，沒有人用這個做商業項目。 pygame其實就是SDL的python綁定，SDL又是基於OpenGL，所以也有人用pygame pyOpenGL做3D示範什麼的。真的要寫遊戲的話pygame的封裝比較底層，不太夠用，很多東西都要自己實現（當然自由度也高）。文件也不太好，好在前人留下了很多文章。拿來練手倒是很不錯的選擇，可以用來實踐很多2D遊戲中常用的想法和演算法。如果是想要直接以上來拿來寫2D遊戲的話還可以選擇cocos2D（注意不是iOS那個，是Python的）這個的API設計的非常好，簡單易用。還有場景管理、內建的控制台等等。可惜也有一年沒更新……雖然作者說會更新啦，估計他主攻Objective-C那個版本的cocos了，畢竟用的人多……幀動畫之類的特性沒有真是很可惜（Objective-C的版本就有T_T）如果是想寫引擎的話可以試試看pyglet。想寫3D試試panda3D或python-orge，這倆我都沒用過，不過大家都這麼說，應該錯不了。總的來說拿python寫遊戲的人少之又少，你寫完了別人玩還要裝環境，打包又各種bug，拿來試驗遊戲中的某種演算法做原型還可以。真正寫還是算了。當然了，題主要是根本就沒打算用pygame寫遊戲就當我什麼都沒說吧…
