Replying to both of these messages because I seem to have missed one.

A bit slower, but audio games are generally not as demanding as their
graphical counterparts. You're also restricted to distributing the
source with your applications as both are interpreted, though there
are utilities for both to convert the scripts to windows executables.

Yeah, that's one of the more advanced features that I like--you can
design what are called "domain-specific languages," mini-programming
languages for doing very specific tasks. See, for instance, how I'm
defining game menus in the game I'm planning to release after Torrent:
menu do
menu("Start game") do
item("Easy") do
WaveManager.difficulty = WaveManager.Easy
Game.start
end
item("Hard") do
WaveManager.difficulty = WaveManager.hard
Game.start
end
end
item("Configure") do
end
item("Exit") do
Game.shutdown
end
end
What I've done here is define a game menu with three items--"Start
game", "Configure" and "Exit." The "Start game" menu item brings up a
submenu with two items, "Easy" and "Hard." Each of these sets
WaveManager.difficulty appropriately and starts the game. The
"Configure" item does nothing for now. "Exit" shuts down the game.
Now, none of that is standard Ruby. I'm basically developing my own
mini-language for defining menus from within Ruby itself, and it's
super easy. This is also very easy to extend to something like, say,
game entity scripting, so you can easily develop mini-languages for
creating missions, levels, etc.:
ship do
name = "CNV Titan"
position = [100, 200, 0]
speed = 0
mode = :peaceful
end
or something similar. The possibilities are quite exhaustive for what
can be accomplished with domain-specific languages.
Anyhow, as I stated, that's a rather advanced feature of Ruby, but it
gives you some sense of what is possible. It's an easy language, but
no toy or Kids Programming Language. :P

Yeah, that's all there is to it. For a good introductory book, see:

No, I didn't say that. As far as I know, it can't. It does, however,
work nicely with SDL which is a DirectX alternative.
