You reach the Crown you win the game. Takes out the tedious roll-off.
I play a variant to this version, which is only a bit longer.
If the first player reachses the Crown of Command,
the Portal of Power is closed for the rest of the Game.
The game ends, when there are no other players left in the inner region
This means, that all players who are not yet in the inner region are (almost) out of the game (Only certain spaces/locations which send You to the plain of peril may get you past the portal of power)
IN consequence, as soon as one player comes towards the plain of fire, the rest will start for the gate, before it is closed - does a good job
