Once A Fool
how do you determine where everyone is once the grid comes out and combat starts. Can I do it randomly, within reason (i.e. "You were searching the east half of the room, so we're going to roll a d4 for which N-S axis square you're in and a d3 for which E-W axis square)? Do I let the player's pick? Before or after the enemies or whatever are revealed?
Consider placing PCs and monsters on the map in reverse initiative order (within reason, of course--hidden creatures should not be placed and a PC should usually start within a certain number of squares of the entrance to a chamber). This provides a fair structure to the placement and also adds a little incentive for the PCs to have high initiative modifiers, as creatures with higher initiative get to be placed in reaction to those with lower initiative.
