Magic: The Gathering - The Precursors is a cooperative board game and card variant of the classic, competitive card game that has players work together in an epic campaign that can span several gaming sessions. It utilizes a slightly altered Commander (EDH) format of MTG.
Similar to Dungeons & Dragons, a Dungeon Master — or a Game Master (GM), in this case — guides up to four other players on a series of six quests, each of which takes about two to three hours to complete.
The players start in one of the zones. If it’s the Red zone, they’ll be facing a Red or Multicoloured commander; the Blue zone, they’ll be facing a Blue or Multicoloured commander; etc. Each quest features a new enemy deck, so no two quests are ever the same.
The GM is given certain card and life advantages over the Precursor heroes, and it is the goal of the Precursors to defeat the GM while working together. Also of note is that the game allows the GM to also play as one of the heroes if they’re up to it. This means that the game supports up to five players.
The game is quite affordable as it allows cards from every single MTG set. The players make their decks with whatever cards they want to use, a single commander (Legendary Creature) overseeing the army of cards.
The board game consists of five different phases, two of which are almost identical to traditional duels. The game’s pretty simple to learn for veteran Magic players, and not much more difficult than the card game itself for new Magic players.
NOTE: This game is unofficial, of course.
