What I miss in Python Game Development

As I said before (and I repeated), if I start a new project, I prefer to work with Python, 'cause I like its huge standard library, its portability and its syntax and this is true for every new project I do for work: such as "building netcdf files", "analize meteorological datas", "manage databases". But I had a big problem for a personal project, a long dreamed chimera never really realized: a videogame. I thought to build a simple shooter, something like the old "galaga" or "space impact", using hardware accelerated graphics for great effects, such as particles and flashes. There are many schools of thought on game development under Python: there's PyGame ones, Pyglet, Pandas, ecc. I would like to talk with you about actual game development in python and reflect about my needs
