Cross platform languages: Theoretically Java is good for this, but
in practice you can also do very well with C/C++, and it's much
faster with a wider existing codebase. It is essential that you have
access to all your target O/S's (or know someone who does) and that
you compile for those O/S's regularly to make sure the code is still
working.

As far as libraries go, you might want to look at SDL -- it's the
one I've heard the most nice things about (www.libsdl.org). It is
LGPL, which means that you should use it as a DLL if you wish to
make a closed-source commercial product, but at least making a
closed source product is legal with the LGPL. SDL lets you use
OpenGL, compiles on several O/S's (Windows, Linux, Beos, and
Macintosh), and does a fairly good job of using hardware
acceleration. It also has a huge number of libraries, for things
like sound, networking, fonts, etc.

Another possibility for cross-platform gaming is ClanLib,
www.clanlib.org. I've only looked at it briefly -- it seems to be
well designed, but I am not sure how flexible it is. ClanLib is
designed for 2d games (but both of your examples, WarCraft and AOE,
are 2d games by the usual definition). These guys have posted a lot
of sample games, many with source code.

Last off, avoiding bugs and leaks mostly requires knowing what
causes them, and coding very carefully and methodically. Don't write
anything beyond midnight, and to paraphrase Einstein, "make it as
simple as possible, but no simpler." The most useful preventative is
a lot of experience.
