In between procrastinating, stalling and working on microchunks of things I should be doing megachunks of . . . I have been looking at simple online games. I could argue that this is research, and in many ways it is.
One of the best is Dicewars. Very similar to the classic Risk, Dicewars is basically a game where you try to conquer the lands of your other rivals. All players are at the mercy of the dice roll. Each piece of land can store up to 8 dice rolls and as the game progresses and it gets down to only a two or three remaining players it can all hinge on a single roll.
