the dice system is fairly easy Zulo.  Basically you roll 2d6 and add that total to your base score.  then add or subtract any penalties.<br/><br/>As far as the grid, once again, it's not too difficult, though i admit it can be a little hard on the eyes.  And it can be a little difficult because the lines don't always stay even.  However, if you just count the *'s you can tell where things are as a rule.<br/><br/>As far as attacking diagonally, i'd allow ranged attackes, and maybe particlerly long weapons, ie spears or halbreds.  And yes, you can attack a person if your directly above or below, ie, B can attack D and vice versa.
