In that thread, "Servant of the Lord" gave this excellent solution for displaying multiple players on a tile which I am going to use for the game.
However, as far as I know, all tile based RPGs have a restriction of 1 player/monster/object on each tile. Although I would like to be innovative and try new game designs, I am a little worried that no one is allowing multiple players to occupy the same tile.
1) Have you seen a tiled based RPG that allow multiple players on the same tile?
2) Do you see any major problem with this approach?
With regards to question 2, I suspect targeting a specific player with a range weapon in a tile with multiple players might cause some problem.
