Light-hearted:
--------------
Cults Across America
(arguably a vicious game, too
)
Vicious bastard:
----------------
Settlers of Catan (2p card version)
Blood Feud: New York
Diplomacy
Logistics/grand strategy:
-------------------------
Empires in Arms
Simulations that should have been on computers, not board:
----------------------------------------------------------
Panzer (the 1979 game)... manual LOS and facing checks
Of those, my favorite would be Cults, because it combines both silly humor
and the potential for very, VERY nasty play.
