I consider myself an expert on games, physical or otherwise, yet "Tartarus" is outside my experience. Describe it, if you please, Your Highness? I wish to know if it is a truly new game or merely a regional variant name for one already in my catalogue (in the same way that "Griffon's Gulch" is functionally identical to "Road to Trottingham.")
Tartarus is a board game for three to six players in which one plays as one of the ancient evils attempting to escape Tartarus (such as Tirek, Lord Havoc and even Discord despite him not being banished there).
The object of the game is to be the first to move from the starting position to the end of the board (thus escaping).
Each of the ancient evils have different abilities which can be used under certain conditions, as well as basic statistics for determining combat situations, and players are also dealt a number of action cards, representing different actions one can perform (or usable items), which they keep on hoof until needed.
At the beginning of one’s turn, one may play any number of cards which are not restricted to specific situations, then one draws what is known as an obstacle card. This obstacle represents a challenge to overcome to advance towards the exit.
During an obstacle, players may choose to assist each other, or sabotage each other (but do not have to do either). Depending on action cards and obstacles, players may need to be on the same space on the board to do this however.
If the obstacle is overcome, the player who drew it advances one space on the board. If not, the player stays put. (However card effects may cause the current player, or other players to advance or retreat regardless of outcome.)
At the end of the turn, players may choose to
draw two new action cards and keep those, or draw three action cards, look at them, and keep one.
As an example turn, one pony starts by playing Abyssal Amulet, which improves combat strength (prudent in case the obstacle is a fight), then draws Chasm. As the player does not have Rope, Teleport or similar card, the player asks the other player at the same space on the board to assist, as two players working together can cross a Chasm.
Once the other player has agreed and the obstacle is overcome, the current player then plays Sudden But Inevitable Betrayal, causing the other player to move back one space rather than forward, while themselves moving forward one space. To end the turn, the player draws two new cards blindly.
It’s partly luck but also a lot of strategy involved. Quite a fun game, though not suited to ponies who are sore losers perhaps.
