The game development has been very "test-driven" in the sense that the game quickly was made playable and that features and changes were added and removed continuously during development. This hopefully improves gameplay, but of course at the expense of dramatically increased development time.
Realms of rivalry was never intended to "soothe the masses", but were made entirely to match the game that we ourselves would like to play - something we have done for many, many hours :-) But of course, some of you might enjoy this game aswell, and that is why we decided to share it with you!.

Games::Alak is a simple game-tree implementation of a gomoku-like game.

SYNOPSIS

% perl -MGames::Alak -e Games::Alak::play
...Or just run Alak.pm as if it were a program...
...Program responds with output, and a prompt:

Lookahead set to 3. I am X, you are O.
Enter h for help
X moves from 1 to 5, yielding .xxxx..oooo
alak>
...and now you enter the commands to play.

This module implements a simple game-tree system for the computer to play against the user in a game of Alak. You can just play the game for fun; or you can use this module as a starting point for understanding game trees (and implementing smarter strategy -- the modules current logic is fairly simple-minded), particularly after reading my Perl Journal #18 article on trees, which discusses this modules implementation of game trees as an example of general tree-shaped data structures.
