[His Divine Shadow]

The game is heavily reliant on the balance between character types and skills. With certain combinations, the odds get heavily stacked against the players, and with other combinations, the players walk all over the Overlord. Which, in certain respects, is a welcome change from Doom, where the game was stacked against the players no matter what.

The expansions can highlight the balance problem as well, since the Overlord gets more tools, so with certain bad character/skill combinations, the game is almost over before the characters get much past the first room.
