Alien Frontiers: Factions
Alien Frontiers: Factions adds a number of items to the Alien Frontiers base game: Ship and colony tokens for a fifth player. Factions (thus the name), with each faction providing its owner a special ability and new orbital facilities under his control. Agendas, which are hidden objectives that allow a player to earn bonus points at game's end or when the agenda is revealed in-game. New Alien Tech cards, such as the Lunar Tunneler, which will allow its owner to pay one fuel to receive an extra ore when using the Lunar Mine. This card's discard power will send all ships docked at the Lunar Mine to the Maintenance Bay, which can be useful when the Mine is clogged with high-value ships.

Ultra Tiny Epic Kingdoms
You are a tiny kingdom with big ambition. You want to expand your population throughout the realms, learn powerful magic, build grand towers, and have your neighbors quiver at the mention of your name. The conflict? All of the other kingdoms want the same thing and there's not enough room for everyone to succeed... In Tiny Epic Kingdoms, a 4x fantasy game in a pocket-size package, each player starts with a unique faction (which has a unique technology tree) and a small territory. Throughout the game, players collect resources, explore other territories, battle each other, research magic, and work to build a great tower to protect their realm. Ultra Tiny Epic Kingdoms (UTEK) is everything Tiny Epic Kingdoms (TEK) is — minus the exploration mini-expansion, but with added solo play — but much smaller. UTEK and TEK are virtually the same game. The only rule difference between the two versions is how units react to the Ruins region and certain faction/territory restrictions exist due to having them back to back on the cards.
