From the introduction:
What is Twilight?
That’s a good question. Twilight is a role-playing game designed to be quick and fun to play, yet offer incredible depth at every level of play from character creation to a trip to the market to a raging battle. Have you ever played a game where you are limited by character classes? The Twilight system allows you to make anyone or anything you can imagine, right off the bat. Have you ever swung a longsword, barely nicked your foe, yet done maximum damage? The Twilight combat system makes sense – you even fight badly when wounded. Have you ever wondered whether that new spell your character researched is particularly overpowered? The Twilight power system breaks magic down into components that can create any spell, game balance guaranteed. (Sadly, it’s unavailable in the demo version.)
And all you need to play is a handful of six-sided dice (the d6). Once you get the hang of it, you won’t even need the rulebook – the system doesn’t use many tables, and the core mechanic is very simple.
And finally, there’s a conversion guide that allows you to convert to or from D&D (3rd edition). Don’t worry, it’s very quick – most of the point totals don’t even have to be changed.
So come on – into the Twilight.
