Isn't this more about IDEs than Python itself? You can easily rename all instances of your variables in pretty much any text editor regardless of the language.

Thanks, I'll look into that.

Yeah I know that, but what can it use as input and how?

How about lisp? It depends on what you mean by versatile though.

Have you considered just doing what you most want to do and getting the money if you happen to get it?

1. With one of these GUI frameworks. I would probably use PyGame and build the GUI elements myself.

2. I don't know, there might be. Or you could just use text files if you don't mind them being readable by the player.

3. I believe you would import all the scripts in your main file (for example import playerInventory) and then use their functions like playerInventory.someFunction(). Unity has the main game loop hidden from you, but it basically calls all the update functions you have in individual scripts every frame and then renders the results.

For optimizing games there are profilers that tell you which parts of the code take the most of the processing time so you can focus on improving those. (It seems Unity comes with one.)

I just made a Bitbucket account yesterday. Private repos are free (for 5 users max) and importing from Github went effortlessly.

This is now also on GOG. I guess they used the Early Access for feedback, but I still hate it when they release on Steam first.

Colobot -- a real-time strategy game that teaches object-oriented programming.

I learned Vim first and switched to Emacs recently for SLIME, and I can say once you learn just the very basics of either you'll be editing as fast or faster than with Notepad++.

Not very unfortunately. It blocks some ads by default, but you need to run a script to convert and use the AdBlock Plus filters, and if you want to add anything to those you need to directly edit the config file.

I believe Privoxy uses less memory and CPU than any plugin (around 10 MB for me right now with a dozen or so heavyish sites in tabs), and blocks ads systemwide.
