Looking at what Chris has developed, I'm seeing a lot of tie-in with the original Esaene rules.
To recap: there were only 3 stats: ST, SK, IQ. What I didn't do as well as Chris was balance the classes like he has.
ST: combat-heavy warriors
SK: dextrous and nimble rogues
IQ: smart guys (like wizards)
In between these, there are
SK-IQ: not sure, but bears watching for development...
I'm intrigued to see how the wizard/sorceror dichotomy shakes out, too.
