Sanctum (1998)

Sanctum is an online, turn-based strategy game for 2 players. It combines the cards of a collectible card game with the map and units of a board game. Its setting is fantasy-based: Cards are called spells, and you cast them by acquiring and paying mana. The game units include many fantasy races, denizens, and cultures, some of which are borrowed from Earth mythology, and some of which are original.
