How did you go about making this?

[reverend]

If you want cross-platform games, you should either try SDL and C++ (illwinter used this for dominions IIRC) or, if you prefer C#, have a look at MONO (www.mono-project.com) which gives you C# and runs on pretty much every system using the MONO runtime.

Java anyone?

Very similar to C#, and cross-platform compatibility is built-in!

FWIW, we've tenatively decided to build our future games on the PopCap Framework, which is now open-source. (http://developer.popcap.com/).

This means we'll still be bound to PCs for the forseeable future (though an eventual Mac port of the framework isn't out of the question), but on the upside, our future games will be faster, smaller, and will run on more machines than Land of Legends.
