GMT Games is a publisher of strategy games, wargames, and eurogames since 1990, headquartered in Hanford, CA
GMT Games announces most of the their games via P500 system. They do not list release dates.
"Once a game is available to order from the P500 list, you decide whether you want the game. If you do, you pre-order it. When we reach 500 buyers, the game has “made the cut" and we begin to wrap up playtesting and begin final editing and prepare for production . Then, when the game gets about 700-750 orders, it is ready for final production."
