4X is an acronym of Explore, Expand, Exploit and Exterminate. 4X games are a subgenre of Strategy and Board games, featuring both Real-Time Strategy games (RTS) and Turn-Based games. 4X games may sound like a novelty, but they've actually been around for a long time. In the 90s, they were already 4X games available to play, but they were outshined by other Strategy games. Enjoy an exciting combination of genres with our 4X games!
