You should know that there's no determental effects... yet. We're slowing rolling out the fatigue system, and we're watching it's balence and trying to get a feel for how it should work without actually imposing any negative effects on the players.
In the next few weeks, we'll be making some changes to it, so if it appears to be way off right now, don't worry about it to much.
After we've established a balance we'll make an announcement concerning when the 'detremental effects' will start to be put in, and how to cope with it so you'll have some time to play with it and get adjusted to the potential changes.
It's worth noting that our expectations are that you shouldn't notice it's effects under normal circumstances, meaning you'll never -have- to eat or do anything else to positively affect your fatigue. The flip side of that coin is thoes of you who think your super-human won't be any more unless you take specific measures to maintain your fatigue. Hopefully this will put an end to the 'sneaks all over the city while carrying 2 tons of gear and spars with his friend to near death and still has enough energy left over to whallop at fight night' syndrome.
This change opens the door for many things which we've wanted for a long time, and is designed to ultimately enhance your experience by providing more options and a more dynamic roleplaying situtation, and providing a more realistic environment without forcing you, the players, to worry about the 'nuiances of real life'.
