Playing the original X-Com just gave me an awesome idea- A co-op computer game where you control some organization/government with gameplay similar to X-Com, but much more in depth in various areas. The basic premise would be, of course, to control an agency to do lots of awesome stuff, and most of the major gameplay would either TBS or RTS. The twist would be that different sections of the agency, under the control of the different players, would be scored separately, and each section would have two roles. The first role would be something combat related, such as ground combat, air combat, and naval combat. The second role would be a secondary role, such as logistics, intelligence, and research. The way it would be set up is that you have to all work together to beat the game, but you would also actively compete against each other.
For example, Player 1 might be in charge of the air forces and logistics, Player 2 might be in charge of ground forces and research, and Player 3 would be in control of Naval forces and intelligence. Player 1 would need to get the other players good weapons and armor and things, but he would try to keep as much of the good stuff for himself, while Player 2 would concentrate research on things like rifles and tanks, and Player 3 would concentrate on learning things about underwater minefield emplacements, or what the specifications of the enemy battleships are. Then, when combat starts, each player will have to mutually support each other. Player 2 would take out enemy SAMs and coastal guns, while Player 3 would bombard land positions and offer ESM support, and Player 1 would help take down enemy fortifications and armor. Then, in the secondary roles, Player 1 would want to have his planes upgraded to have lasers, while Player 2 would want a new shipment of artillery. Since neither player can get those things by themselves, they would need the other players to do those things for them. But at the same time, if you help them too much, then you take away an edge your faction would need, and the other player might start getting more kills/points. The game would be just as much about blowing up aliens/russians/koreans/nazis/demons as it would be about trading favors, backstabbing, and grand strategy.
TL;DR/Didn't Understand- A co-op strategy game where each player is in charge of either logistics, research, intellegence, etc, and must limit how much they help other players, while getting other players to help them.
