There are a ton of "new basic" basics out there. I played with over a dozen free ones before I finally decided on one. What I ended up with wouldnt suit you. The give and take for my choice was based on scripting (text handling, command line calls, worked for windows dos and linux, compiled) which took away much from graphics, sound, user interface, ongoing major support and add-on libraries. But I remember going thru alot of variants which were very GUI and excellent environments for writing your own game. Here is a good starting point for checking them all out....

If you are really serious about using Python for games then you might check this out...

Most of the "python" games shifted to Delphi for major releases. (dont I remember early SE along those lines?)
I could probaby find something for games and Delphi if you like.
