The game of Twilight is a small scale skirmish game allowing players to take the role of either the Devanu or the Fubarnii in scenario driven encounters. The full rules are available from Hasslefree, which include lots more background and details, but I always like to have a 'look under the bonnet' before I buy a new game, so here are the basic rules, along with force lists for the Devanu and the Fubarnii, and three scenarios that make use of the first Twilight releases.
While you probably have most of the components necessary to play, the game does require 'combat stones' for each player (sold with the rules, or available from Hasslefree). While these do add a lot to the feel of the game, you can make do with two sets of different coloured dice, using a 1-3 as a failure and a 4-6 as a success.
If you try these out I would love to know what you think - you can easily find me over on the Forum of Doom. I've playtested with several different groups of people and the balance is about right once both players have got the hang of the culture they are using (although it can appear very imbalanced initially due to the distinctive styles of play for the two sides!). We'll be expanding the rules soon, so you can expect to see updates and experimental rules on here in the near future.
Hope you enjoy the game, and I look forward to hearing your opinions!

Sorry the files are a little bit on the big side at the moment. When I get the chance I'll edit them down to something more manageable!
